-Subject: [PATCH] irq-bcm2836: Prevent spurious interrupts, and trap them early
-
-The old arch-specific IRQ macros included a dsb to ensure the
-write to clear the mailbox interrupt completed before returning
-from the interrupt. The BCM2836 irqchip driver needs the same
-precaution to avoid spurious interrupts.
-
-Spurious interrupts are still possible for other reasons,
-though, so trap them early.

-Add a duplicate irq range with an offset on the hwirq's so the
-driver can detect that enable_fiq() is used.
-Tested with downstream dwc_otg USB controller driver.

-Subject: [PATCH] pinctrl-bcm2835: Fix interrupt handling for GPIOs 28-31 and
- 46-53
-
-Contrary to the documentation, the BCM2835 GPIO controller actually has
-four interrupt lines - one each for the three IRQ groups and one common. Rather
-confusingly, the GPIO interrupt groups don't correspond directly with the GPIO
-control banks. Instead, GPIOs 0-27 generate IRQ GPIO0, 28-45 GPIO1 and
-46-53 GPIO2.
-
-Awkwardly, the GPIOS for IRQ GPIO1 straddle two 32-entry GPIO banks, so it is
-cleaner to split out a function to process the interrupts for a single GPIO
-bank.
-
-This bug has only just been observed because GPIOs above 27 can only be
-accessed on an old Raspberry Pi with the optional P5 header fitted, where
-the pins are often used for I2S instead.

- DTB
-
-Although the GPIO controller can generate three interrupts (four counting
-the common one), the device tree files currently only specify two. In the
-absence of the third, simply don't register that interrupt (as opposed to
-registering 0), which has the effect of making it impossible to generate
-interrupts for GPIOs 46-53 which, since they share pins with the SD card
-interface, is unlikely to be a problem.

-Subject: [PATCH] spi-bcm2835: Support pin groups other than 7-11
-
-The spi-bcm2835 driver automatically uses GPIO chip-selects due to
-some unreliability of the native ones. In doing so it chooses the
-same pins as the native chip-selects would use, but the existing
-code always uses pins 7 and 8, wherever the SPI function is mapped.
-
-Search the pinctrl group assigned to the driver for pins that
-correspond to native chip-selects, and use those for GPIO chip-
-selects.

-RPi commit 62c05a0b5328d9376d39c9e74da10b8a2465c234 ("ASoC: BCM2708:
-Add 24 bit support")
-
-This adds 24 bit support to the I2S driver of the BCM2708.
-Besides enabling the 24 bit flags, it includes two bug fixes:
-
-MMAP is not supported. Claiming this leads to strange issues
-when the format of driver and file do not match.
-
-The datasheet states that the width extension bit should be set
-for widths greater than 24, but greater or equal would be correct.
-This follows from the definition of the width field.

-
-Add FIQ patch to dwc_otg driver. Enable with dwc_otg.fiq_fix_enable=1. Should give about 10% more ARM performance.
-Thanks to Gordon and Costas
-
-Avoid dynamic memory allocation for channel lock in USB driver. Thanks ddv2005.
-
-Add NAK holdoff scheme. Enabled by default, disable with dwc_otg.nak_holdoff_enable=0. Thanks gsh
-
-Make sure we wait for the reset to finish
-
-dwc_otg: fix bug in dwc_otg_hcd.c resulting in silent kernel
-	 memory corruption, escalating to OOPS under high USB load.
-
-dwc_otg: Fix unsafe access of QTD during URB enqueue
-
-In dwc_otg_hcd_urb_enqueue during qtd creation, it was possible that the
-transaction could complete almost immediately after the qtd was assigned
-to a host channel during URB enqueue, which meant the qtd pointer was no
-longer valid having been completed and removed. Usually, this resulted in
-an OOPS during URB submission. By predetermining whether transactions
-need to be queued or not, this unsafe pointer access is avoided.
-
-This bug was only evident on the Pi model A where a device was attached
-that had no periodic endpoints (e.g. USB pendrive or some wlan devices).
-
-dwc_otg: Fix incorrect URB allocation error handling
-
-If the memory allocation for a dwc_otg_urb failed, the kernel would OOPS
-because for some reason a member of the *unallocated* struct was set to
-zero. Error handling changed to fail correctly.
-
-dwc_otg: fix potential use-after-free case in interrupt handler
-
-If a transaction had previously aborted, certain interrupts are
-enabled to track error counts and reset where necessary. On IN
-endpoints the host generates an ACK interrupt near-simultaneously
-with completion of transfer. In the case where this transfer had
-previously had an error, this results in a use-after-free on
-the QTD memory space with a 1-byte length being overwritten to
-0x00.
-
-dwc_otg: add handling of SPLIT transaction data toggle errors
-
-Previously a data toggle error on packets from a USB1.1 device behind
-a TT would result in the Pi locking up as the driver never handled
-the associated interrupt. Patch adds basic retry mechanism and
-interrupt acknowledgement to cater for either a chance toggle error or
-for devices that have a broken initial toggle state (FT8U232/FT232BM).
-
-dwc_otg: implement tasklet for returning URBs to usbcore hcd layer
-
-The dwc_otg driver interrupt handler for transfer completion will spend
-a very long time with interrupts disabled when a URB is completed -
-this is because usb_hcd_giveback_urb is called from within the handler
-which for a USB device driver with complicated processing (e.g. webcam)
-will take an exorbitant amount of time to complete. This results in
-missed completion interrupts for other USB packets which lead to them
-being dropped due to microframe overruns.
-
-This patch splits returning the URB to the usb hcd layer into a
-high-priority tasklet. This will have most benefit for isochronous IN
-transfers but will also have incidental benefit where multiple periodic
-devices are active at once.
-
-dwc_otg: fix NAK holdoff and allow on split transactions only
-
-This corrects a bug where if a single active non-periodic endpoint
-had at least one transaction in its qh, on frnum == MAX_FRNUM the qh
-would get skipped and never get queued again. This would result in
-a silent device until error detection (automatic or otherwise) would
-either reset the device or flush and requeue the URBs.
-
-Additionally the NAK holdoff was enabled for all transactions - this
-would potentially stall a HS endpoint for 1ms if a previous error state
-enabled this interrupt and the next response was a NAK. Fix so that
-only split transactions get held off.
-
-dwc_otg: Call usb_hcd_unlink_urb_from_ep with lock held in completion handler
-
-usb_hcd_unlink_urb_from_ep must be called with the HCD lock held.  Calling it
-asynchronously in the tasklet was not safe (regression in
-c4564d4a1a0a9b10d4419e48239f5d99e88d2667).
-
-This change unlinks it from the endpoint prior to queueing it for handling in
-the tasklet, and also adds a check to ensure the urb is OK to be unlinked
-before doing so.
-
-NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb
-when a USB device was unplugged/replugged during data transfer.  This effect
-was reproduced using automated USB port power control, hundreds of replug
-events were performed during active transfers to confirm that the problem was
-eliminated.
-
-USB fix using a FIQ to implement split transactions
-
-This commit adds a FIQ implementaion that schedules
-the split transactions using a FIQ so we don't get
-held off by the interrupt latency of Linux
-
-dwc_otg: fix device attributes and avoid kernel warnings on boot
-
-dcw_otg: avoid logging function that can cause panics
-
-See: https://github.com/raspberrypi/firmware/issues/21
-Thanks to cleverca22 for fix
-
-dwc_otg: mask correct interrupts after transaction error recovery
-
-The dwc_otg driver will unmask certain interrupts on a transaction
-that previously halted in the error state in order to reset the
-QTD error count. The various fine-grained interrupt handlers do not
-consider that other interrupts besides themselves were unmasked.
-
-By disabling the two other interrupts only ever enabled in DMA mode
-for this purpose, we can avoid unnecessary function calls in the
-IRQ handler. This will also prevent an unneccesary FIQ interrupt
-from being generated if the FIQ is enabled.
-
-dwc_otg: fiq: prevent FIQ thrash and incorrect state passing to IRQ
-
-In the case of a transaction to a device that had previously aborted
-due to an error, several interrupts are enabled to reset the error
-count when a device responds. This has the side-effect of making the
-FIQ thrash because the hardware will generate multiple instances of
-a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK
-on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the
-associated interrupts.
-
-Additionally, on non-split transactions make sure that only unmasked
-interrupts are cleared. This caused a hard-to-trigger but serious
-race condition when you had the combination of an endpoint awaiting
-error recovery and a transaction completed on an endpoint - due to
-the sequencing and timing of interrupts generated by the dwc_otg core,
-it was possible to confuse the IRQ handler.
-
-Fix function tracing
-
-dwc_otg: whitespace cleanup in dwc_otg_urb_enqueue
-
-dwc_otg: prevent OOPSes during device disconnects
-
-The dwc_otg_urb_enqueue function is thread-unsafe. In particular the
-access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and
-friends does not occur within a critical section and so if a device
-was unplugged during activity there was a high chance that the
-usbcore hub_thread would try to disable the endpoint with partially-
-formed entries in the URB queue. This would result in BUG() or null
-pointer dereferences.
-
-Fix so that access of urb->hcpriv, enqueuing to the hardware and
-adding to usbcore endpoint URB lists is contained within a single
-critical section.
-
-dwc_otg: prevent BUG() in TT allocation if hub address is > 16
-
-A fixed-size array is used to track TT allocation. This was
-previously set to 16 which caused a crash because
-dwc_otg_hcd_allocate_port would read past the end of the array.
-
-This was hit if a hub was plugged in which enumerated as addr > 16,
-due to previous device resets or unplugs.
-
-Also add #ifdef FIQ_DEBUG around hcd->hub_port_alloc[], which grows
-to a large size if 128 hub addresses are supported. This field is
-for debug only for tracking which frame an allocate happened in.
-
-dwc_otg: make channel halts with unknown state less damaging
-
-If the IRQ received a channel halt interrupt through the FIQ
-with no other bits set, the IRQ would not release the host
-channel and never complete the URB.
-
-Add catchall handling to treat as a transaction error and retry.
-
-dwc_otg: fiq_split: use TTs with more granularity
-
-This fixes certain issues with split transaction scheduling.
-
-- Isochronous multi-packet OUT transactions now hog the TT until
-  they are completed - this prevents hubs aborting transactions
-  if they get a periodic start-split out-of-order
-- Don't perform TT allocation on non-periodic endpoints - this
-  allows simultaneous use of the TT's bulk/control and periodic
-  transaction buffers
-
-This commit will mainly affect USB audio playback.
-
-dwc_otg: fix potential sleep while atomic during urb enqueue
-
-Fixes a regression introduced with eb1b482a. Kmalloc called from
-dwc_otg_hcd_qtd_add / dwc_otg_hcd_qtd_create did not always have
-the GPF_ATOMIC flag set. Force this flag when inside the larger
-critical section.
-
-dwc_otg: make fiq_split_enable imply fiq_fix_enable
-
-Failing to set up the FIQ correctly would result in
-"IRQ 32: nobody cared" errors in dmesg.
-
-dwc_otg: prevent crashes on host port disconnects
-
-Fix several issues resulting in crashes or inconsistent state
-if a Model A root port was disconnected.
-
-- Clean up queue heads properly in kill_urbs_in_qh_list by
-  removing the empty QHs from the schedule lists
-- Set the halt status properly to prevent IRQ handlers from
-  using freed memory
-- Add fiq_split related cleanup for saved registers
-- Make microframe scheduling reclaim host channels if
-  active during a disconnect
-- Abort URBs with -ESHUTDOWN status response, informing
-  device drivers so they respond in a more correct fashion
-  and don't try to resubmit URBs
-- Prevent IRQ handlers from attempting to handle channel
-  interrupts if the associated URB was dequeued (and the
-  driver state was cleared)
-
-dwc_otg: prevent leaking URBs during enqueue
-
-A dwc_otg_urb would get leaked if the HCD enqueue function
-failed for any reason. Free the URB at the appropriate points.
-
-dwc_otg: Enable NAK holdoff for control split transactions
-
-Certain low-speed devices take a very long time to complete a
-data or status stage of a control transaction, producing NAK
-responses until they complete internal processing - the USB2.0
-spec limit is up to 500mS. This causes the same type of interrupt
-storm as seen with USB-serial dongles prior to c8edb238.
-
-In certain circumstances, usually while booting, this interrupt
-storm could cause SD card timeouts.
-
-dwc_otg: Fix for occasional lockup on boot when doing a USB reset
-
-dwc_otg: Don't issue traffic to LS devices in FS mode
-
-Issuing low-speed packets when the root port is in full-speed mode
-causes the root port to stop responding. Explicitly fail when
-enqueuing URBs to a LS endpoint on a FS bus.
-
-Fix ARM architecture issue with local_irq_restore()
-
-If local_fiq_enable() is called before a local_irq_restore(flags) where
-the flags variable has the F bit set, the FIQ will be erroneously disabled.
-
-Fixup arch_local_irq_restore to avoid trampling the F bit in CPSR.
-
-Also fix some of the hacks previously implemented for previous dwc_otg
-incarnations.
-
-dwc_otg: fiq_fsm: Base commit for driver rewrite
-
-This commit removes the previous FIQ fixes entirely and adds fiq_fsm.
-
-This rewrite features much more complete support for split transactions
-and takes into account several OTG hardware bugs. High-speed
-isochronous transactions are also capable of being performed by fiq_fsm.
-
-All driver options have been removed and replaced with:
-  - dwc_otg.fiq_enable (bool)
-  - dwc_otg.fiq_fsm_enable (bool)
-  - dwc_otg.fiq_fsm_mask (bitmask)
-  - dwc_otg.nak_holdoff (unsigned int)
-
-Defaults are specified such that fiq_fsm behaves similarly to the
-previously implemented FIQ fixes.
-
-fiq_fsm: Push error recovery into the FIQ when fiq_fsm is used
-
-If the transfer associated with a QTD failed due to a bus error, the HCD
-would retry the transfer up to 3 times (implementing the USB2.0
-three-strikes retry in software).
-
-Due to the masking mechanism used by fiq_fsm, it is only possible to pass
-a single interrupt through to the HCD per-transfer.
-
-In this instance host channels would fall off the radar because the error
-reset would function, but the subsequent channel halt would be lost.
-
-Push the error count reset into the FIQ handler.
-
-fiq_fsm: Implement timeout mechanism
-
-For full-speed endpoints with a large packet size, interrupt latency
-runs the risk of the FIQ starting a transaction too late in a full-speed
-frame. If the device is still transmitting data when EOF2 for the
-downstream frame occurs, the hub will disable the port. This change is
-not reflected in the hub status endpoint and the device becomes
-unresponsive.
-
-Prevent high-bandwidth transactions from being started too late in a
-frame. The mechanism is not guaranteed: a combination of bit stuffing
-and hub latency may still result in a device overrunning.
-
-fiq_fsm: fix bounce buffer utilisation for Isochronous OUT
-
-Multi-packet isochronous OUT transactions were subject to a few bounday
-bugs. Fix them.
-
-Audio playback is now much more robust: however, an issue stands with
-devices that have adaptive sinks - ALSA plays samples too fast.
-
-dwc_otg: Return full-speed frame numbers in HS mode
-
-The frame counter increments on every *microframe* in high-speed mode.
-Most device drivers expect this number to be in full-speed frames - this
-caused considerable confusion to e.g. snd_usb_audio which uses the
-frame counter to estimate the number of samples played.
-
-fiq_fsm: save PID on completion of interrupt OUT transfers
-
-Also add edge case handling for interrupt transports.
-
-Note that for periodic split IN, data toggles are unimplemented in the
-OTG host hardware - it unconditionally accepts any PID.
-
-fiq_fsm: add missing case for fiq_fsm_tt_in_use()
-
-Certain combinations of bitrate and endpoint activity could
-result in a periodic transaction erroneously getting started
-while the previous Isochronous OUT was still active.
-
-fiq_fsm: clear hcintmsk for aborted transactions
-
-Prevents the FIQ from erroneously handling interrupts
-on a timed out channel.
-
-fiq_fsm: enable by default
-
-fiq_fsm: fix dequeues for non-periodic split transactions
-
-If a dequeue happened between the SSPLIT and CSPLIT phases of the
-transaction, the HCD would never receive an interrupt.
-
-fiq_fsm: Disable by default
-
-fiq_fsm: Handle HC babble errors
-
-The HCTSIZ transfer size field raises a babble interrupt if
-the counter wraps. Handle the resulting interrupt in this case.
-
-dwc_otg: fix interrupt registration for fiq_enable=0
-
-Additionally make the module parameter conditional for wherever
-hcd->fiq_state is touched.
-
-fiq_fsm: Enable by default
-
-dwc_otg: Fix various issues with root port and transaction errors
-
-Process the host port interrupts correctly (and don't trample them).
-Root port hotplug now functional again.
-
-Fix a few thinkos with the transaction error passthrough for fiq_fsm.
-
-fiq_fsm: Implement hack for Split Interrupt transactions
-
-Hubs aren't too picky about which endpoint we send Control type split
-transactions to. By treating Interrupt transfers as Control, it is
-possible to use the non-periodic queue in the OTG core as well as the
-non-periodic FIFOs in the hub itself. This massively reduces the
-microframe exclusivity/contention that periodic split transactions
-otherwise have to enforce.
-
-It goes without saying that this is a fairly egregious USB specification
-violation, but it works.
-
-Original idea by Hans Petter Selasky @ FreeBSD.org.
-
-dwc_otg: FIQ support on SMP. Set up FIQ stack and handler on Core 0 only.
-
-dwc_otg: introduce fiq_fsm_spin(un|)lock()
-
-SMP safety for the FIQ relies on register read-modify write cycles being
-completed in the correct order. Several places in the DWC code modify
-registers also touched by the FIQ. Protect these by a bare-bones lock
-mechanism.
-
-This also makes it possible to run the FIQ and IRQ handlers on different
-cores.
-
-fiq_fsm: fix build on bcm2708 and bcm2709 platforms
-
-dwc_otg: put some barriers back where they should be for UP
-
-bcm2709/dwc_otg: Setup FIQ on core 1 if >1 core active
-
-dwc_otg: fixup read-modify-write in critical paths
-
-Be more careful about read-modify-write on registers that the FIQ
-also touches.
-
-Guard fiq_fsm_spin_lock with fiq_enable check
-
-fiq_fsm: Falling out of the state machine isn't fatal
-
-This edge case can be hit if the port is disabled while the FIQ is
-in the middle of a transaction. Make the effects less severe.
-
-Also get rid of the useless return value.
-
-squash: dwc_otg: Allow to build without SMP
-
-usb: core: make overcurrent messages more prominent
-
-Hub overcurrent messages are more serious than "debug". Increase loglevel.
-
-usb: dwc_otg: Don't use dma_to_virt()
-
-Commit 6ce0d20 changes dma_to_virt() which breaks this driver.
-Open code the old dma_to_virt() implementation to work around this.
-
-Limit the use of __bus_to_virt() to cases where transfer_buffer_length
-is set and transfer_buffer is not set. This is done to increase the
-chance that this driver will also work on ARCH_BCM2835.
-
-transfer_buffer should not be NULL if the length is set, but the
-comment in the code indicates that there are situations where this
-might happen. drivers/usb/isp1760/isp1760-hcd.c also has a similar
-comment pointing to a possible: 'usb storage / SCSI bug'.

-+ * The File-backed Storage Gadget acts as a USB Mass Storage device,
-+ * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
-+ * to providing an example of a genuinely useful gadget driver for a USB
-+ * device, it also illustrates a technique of double-buffering for increased
-+ * throughput.  Last but not least, it gives an easy way to probe the
-+ * behavior of the Mass Storage drivers in a USB host.
-+ *
-+ * Backing storage is provided by a regular file or a block device, specified
-+ * by the "file" module parameter.  Access can be limited to read-only by
-+ * setting the optional "ro" module parameter.  (For CD-ROM emulation,
-+ * access is always read-only.)  The gadget will indicate that it has
-+ * removable media if the optional "removable" module parameter is set.
-+ *
-+ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
-+ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
-+ * by the optional "transport" module parameter.  It also supports the
-+ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
-+ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
-+ * the optional "protocol" module parameter.  In addition, the default
-+ * Vendor ID, Product ID, release number and serial number can be overridden.
-+ *
-+ * There is support for multiple logical units (LUNs), each of which has
-+ * its own backing file.  The number of LUNs can be set using the optional
-+ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
-+ * files are specified using comma-separated lists for "file" and "ro".
-+ * The default number of LUNs is taken from the number of "file" elements;
-+ * it is 1 if "file" is not given.  If "removable" is not set then a backing
-+ * file must be specified for each LUN.  If it is set, then an unspecified
-+ * or empty backing filename means the LUN's medium is not loaded.  Ideally
-+ * each LUN would be settable independently as a disk drive or a CD-ROM
-+ * drive, but currently all LUNs have to be the same type.  The CD-ROM
-+ * emulation includes a single data track and no audio tracks; hence there
-+ * need be only one backing file per LUN.
-+ *
-+ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
-+ * needed (an interrupt-out endpoint is also needed for CBI).  The memory
-+ * requirement amounts to two 16K buffers, size configurable by a parameter.
-+ * Support is included for both full-speed and high-speed operation.
-+ *
-+ * Note that the driver is slightly non-portable in that it assumes a
-+ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
-+ * interrupt-in endpoints.  With most device controllers this isn't an
-+ * issue, but there may be some with hardware restrictions that prevent
-+ * a buffer from being used by more than one endpoint.
-+ *
-+ * Module options:
-+ *
-+ *	file=filename[,filename...]
-+ *				Required if "removable" is not set, names of
-+ *					the files or block devices used for
-+ *					backing storage
-+ *	serial=HHHH...		Required serial number (string of hex chars)
-+ *	ro=b[,b...]		Default false, booleans for read-only access
-+ *	removable		Default false, boolean for removable media
-+ *	luns=N			Default N = number of filenames, number of
-+ *					LUNs to support
-+ *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
-+ *					in SCSI WRITE(10,12) commands
-+ *	stall			Default determined according to the type of
-+ *					USB device controller (usually true),
-+ *					boolean to permit the driver to halt
-+ *					bulk endpoints
-+ *	cdrom			Default false, boolean for whether to emulate
-+ *					a CD-ROM drive
-+ *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
-+ *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
-+ *					ATAPI, QIC, UFI, 8070, or SCSI;
-+ *					also 1 - 6)
-+ *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
-+ *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
-+ *	release=0xRRRR		Override the USB release number (bcdDevice)
-+ *	buflen=N		Default N=16384, buffer size used (will be
-+ *					rounded down to a multiple of
-+ *					PAGE_CACHE_SIZE)
-+ *
-+ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
-+ * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
-+ * default values are used for everything else.
-+ *
-+ * The pathnames of the backing files and the ro settings are available in
-+ * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
-+ * the gadget's sysfs directory.  If the "removable" option is set, writing to
-+ * these files will simulate ejecting/loading the medium (writing an empty
-+ * line means eject) and adjusting a write-enable tab.  Changes to the ro
-+ * setting are not allowed when the medium is loaded or if CD-ROM emulation
-+ * is being used.
-+ *
-+ * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
-+ * The driver's SCSI command interface was based on the "Information
-+ * technology - Small Computer System Interface - 2" document from
-+ * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
-+ * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
-+ * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
-+ * "Universal Serial Bus Mass Storage Class UFI Command Specification"
-+ * document, Revision 1.0, December 14, 1998, available at
-+ * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-+
-+
-+/*
-+ *				Driver Design
-+ *
-+ * The FSG driver is fairly straightforward.  There is a main kernel
-+ * thread that handles most of the work.  Interrupt routines field
-+ * callbacks from the controller driver: bulk- and interrupt-request
-+ * completion notifications, endpoint-0 events, and disconnect events.
-+ * Completion events are passed to the main thread by wakeup calls.  Many
-+ * ep0 requests are handled at interrupt time, but SetInterface,
-+ * SetConfiguration, and device reset requests are forwarded to the
-+ * thread in the form of "exceptions" using SIGUSR1 signals (since they
-+ * should interrupt any ongoing file I/O operations).
-+ *
-+ * The thread's main routine implements the standard command/data/status
-+ * parts of a SCSI interaction.  It and its subroutines are full of tests
-+ * for pending signals/exceptions -- all this polling is necessary since
-+ * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
-+ * indication that the driver really wants to be running in userspace.)
-+ * An important point is that so long as the thread is alive it keeps an
-+ * open reference to the backing file.  This will prevent unmounting
-+ * the backing file's underlying filesystem and could cause problems
-+ * during system shutdown, for example.  To prevent such problems, the
-+ * thread catches INT, TERM, and KILL signals and converts them into
-+ * an EXIT exception.
-+ *
-+ * In normal operation the main thread is started during the gadget's
-+ * fsg_bind() callback and stopped during fsg_unbind().  But it can also
-+ * exit when it receives a signal, and there's no point leaving the
-+ * gadget running when the thread is dead.  So just before the thread
-+ * exits, it deregisters the gadget driver.  This makes things a little
-+ * tricky: The driver is deregistered at two places, and the exiting
-+ * thread can indirectly call fsg_unbind() which in turn can tell the
-+ * thread to exit.  The first problem is resolved through the use of the
-+ * REGISTERED atomic bitflag; the driver will only be deregistered once.
-+ * The second problem is resolved by having fsg_unbind() check
-+ * fsg->state; it won't try to stop the thread if the state is already
-+ * FSG_STATE_TERMINATED.
-+ *
-+ * To provide maximum throughput, the driver uses a circular pipeline of
-+ * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
-+ * arbitrarily long; in practice the benefits don't justify having more
-+ * than 2 stages (i.e., double buffering).  But it helps to think of the
-+ * pipeline as being a long one.  Each buffer head contains a bulk-in and
-+ * a bulk-out request pointer (since the buffer can be used for both
-+ * output and input -- directions always are given from the host's
-+ * point of view) as well as a pointer to the buffer and various state
-+ * variables.
-+ *
-+ * Use of the pipeline follows a simple protocol.  There is a variable
-+ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
-+ * At any time that buffer head may still be in use from an earlier
-+ * request, so each buffer head has a state variable indicating whether
-+ * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
-+ * buffer head to be EMPTY, filling the buffer either by file I/O or by
-+ * USB I/O (during which the buffer head is BUSY), and marking the buffer
-+ * head FULL when the I/O is complete.  Then the buffer will be emptied
-+ * (again possibly by USB I/O, during which it is marked BUSY) and
-+ * finally marked EMPTY again (possibly by a completion routine).
-+ *
-+ * A module parameter tells the driver to avoid stalling the bulk
-+ * endpoints wherever the transport specification allows.  This is
-+ * necessary for some UDCs like the SuperH, which cannot reliably clear a
-+ * halt on a bulk endpoint.  However, under certain circumstances the
-+ * Bulk-only specification requires a stall.  In such cases the driver
-+ * will halt the endpoint and set a flag indicating that it should clear
-+ * the halt in software during the next device reset.  Hopefully this
-+ * will permit everything to work correctly.  Furthermore, although the
-+ * specification allows the bulk-out endpoint to halt when the host sends
-+ * too much data, implementing this would cause an unavoidable race.
-+ * The driver will always use the "no-stall" approach for OUT transfers.
-+ *
-+ * One subtle point concerns sending status-stage responses for ep0
-+ * requests.  Some of these requests, such as device reset, can involve
-+ * interrupting an ongoing file I/O operation, which might take an
-+ * arbitrarily long time.  During that delay the host might give up on
-+ * the original ep0 request and issue a new one.  When that happens the
-+ * driver should not notify the host about completion of the original
-+ * request, as the host will no longer be waiting for it.  So the driver
-+ * assigns to each ep0 request a unique tag, and it keeps track of the
-+ * tag value of the request associated with a long-running exception
-+ * (device-reset, interface-change, or configuration-change).  When the
-+ * exception handler is finished, the status-stage response is submitted
-+ * only if the current ep0 request tag is equal to the exception request
-+ * tag.  Thus only the most recently received ep0 request will get a
-+ * status-stage response.
-+ *
-+ * Warning: This driver source file is too long.  It ought to be split up
-+ * into a header file plus about 3 separate .c files, to handle the details
-+ * of the Gadget, USB Mass Storage, and SCSI protocols.

-+
-+dwc_read_reg32() and friends now take an additional parameter, a pointer to an
-+IO context struct. The IO context struct should live in an os-dependent struct
-+in your driver. As an example, the dwc_usb3 driver has an os-dependent struct
-+named 'os_dep' embedded in the main device struct. So there these calls look
-+like this:
-+
-+	dwc_read_reg32(&usb3_dev->os_dep.ioctx, &pcd->dev_global_regs->dcfg);
-+
-+	dwc_write_reg32(&usb3_dev->os_dep.ioctx,
-+			&pcd->dev_global_regs->dcfg, 0);
-+
-+Note that for the existing Linux driver ports, it is not necessary to actually
-+define the 'ioctx' member in the os-dependent struct. Since Linux does not
-+require an IO context, its macros for dwc_read_reg32() and friends do not
-+use the context pointer, so it is optimized away by the compiler. But it is
-+necessary to add the pointer parameter to all of the call sites, to be ready
-+for any future ports (such as FreeBSD) which do require an IO context.
-+
-+
-+Similarly, dwc_alloc(), dwc_alloc_atomic(), dwc_strdup(), and dwc_free() now
-+take an additional parameter, a pointer to a memory context. Examples:
-+
-+	addr = dwc_alloc(&usb3_dev->os_dep.memctx, size);
-+
-+	dwc_free(&usb3_dev->os_dep.memctx, addr);
-+
-+Again, for the Linux ports, it is not necessary to actually define the memctx
-+member, but it is necessary to add the pointer parameter to all of the call
-+sites.
-+
-+
-+Same for dwc_dma_alloc() and dwc_dma_free(). Examples:
-+
-+	virt_addr = dwc_dma_alloc(&usb3_dev->os_dep.dmactx, size, &phys_addr);
-+
-+	dwc_dma_free(&usb3_dev->os_dep.dmactx, size, virt_addr, phys_addr);
-+
-+
-+Same for dwc_mutex_alloc() and dwc_mutex_free(). Examples:
-+
-+	mutex = dwc_mutex_alloc(&usb3_dev->os_dep.mtxctx);
-+
-+	dwc_mutex_free(&usb3_dev->os_dep.mtxctx, mutex);
-+
-+
-+Same for dwc_spinlock_alloc() and dwc_spinlock_free(). Examples:
-+
-+	lock = dwc_spinlock_alloc(&usb3_dev->osdep.splctx);
-+
-+	dwc_spinlock_free(&usb3_dev->osdep.splctx, lock);
-+
-+
-+Same for dwc_timer_alloc(). Example:
-+
-+	timer = dwc_timer_alloc(&usb3_dev->os_dep.tmrctx, "dwc_usb3_tmr1",
-+				cb_func, cb_data);
-+
-+
-+Same for dwc_waitq_alloc(). Example:
-+
-+	waitq = dwc_waitq_alloc(&usb3_dev->os_dep.wtqctx);
-+
-+
-+Same for dwc_thread_run(). Example:
-+
-+	thread = dwc_thread_run(&usb3_dev->os_dep.thdctx, func,
-+				"dwc_usb3_thd1", data);
-+
-+
-+Same for dwc_workq_alloc(). Example:
-+
-+	workq = dwc_workq_alloc(&usb3_dev->osdep.wkqctx, "dwc_usb3_wkq1");
-+
-+
-+Same for dwc_task_alloc(). Example:
-+
-+	task = dwc_task_alloc(&usb3_dev->os_dep.tskctx, "dwc_usb3_tsk1",
-+			      cb_func, cb_data);
-+
-+
-+In addition to the context pointer additions, a few core functions have had
-+other changes made to their parameters:
-+
-+The 'flags' parameter to dwc_spinlock_irqsave() and dwc_spinunlock_irqrestore()
-+has been changed from a uint64_t to a dwc_irqflags_t.
-+
-+dwc_thread_should_stop() now takes a 'dwc_thread_t *' parameter, because the
-+FreeBSD equivalent of that function requires it.
-+
-+And, in addition to the context pointer, dwc_task_alloc() also adds a
-+'char *name' parameter, to be consistent with dwc_thread_run() and
-+dwc_workq_alloc(), and because the FreeBSD equivalent of that function
-+requires a unique name.
-+
-+
-+Here is a complete list of the core functions that now take a pointer to a
-+context as their first parameter:
-+
-+	dwc_read_reg32
-+	dwc_read_reg64
-+	dwc_write_reg32
-+	dwc_write_reg64
-+	dwc_modify_reg32
-+	dwc_modify_reg64
-+	dwc_alloc
-+	dwc_alloc_atomic
-+	dwc_strdup
-+	dwc_free
-+	dwc_dma_alloc
-+	dwc_dma_free
-+	dwc_mutex_alloc
-+	dwc_mutex_free
-+	dwc_spinlock_alloc
-+	dwc_spinlock_free
-+	dwc_timer_alloc
-+	dwc_waitq_alloc
-+	dwc_thread_run
-+	dwc_workq_alloc
-+	dwc_task_alloc     Also adds a 'char *name' as its 2nd parameter
-+
-+And here are the core functions that have other changes to their parameters:
-+
-+	dwc_spinlock_irqsave      'flags' param is now a 'dwc_irqflags_t *'
-+	dwc_spinunlock_irqrestore 'flags' param is now a 'dwc_irqflags_t'
-+	dwc_thread_should_stop    Adds a 'dwc_thread_t *' parameter
-+
-+
-+
-+The changes to the core functions also require some of the other library
-+functions to change:
-+
-+	dwc_cc_if_alloc() and dwc_cc_if_free() now take a 'void *memctx'
-+	(for memory allocation) as the 1st param and a 'void *mtxctx'
-+	(for mutex allocation) as the 2nd param.
-+
-+	dwc_cc_clear(), dwc_cc_add(), dwc_cc_change(), dwc_cc_remove(),
-+	dwc_cc_data_for_save(), and dwc_cc_restore_from_data() now take a
-+	'void *memctx' as the 1st param.
-+
-+	dwc_dh_modpow(), dwc_dh_pk(), and dwc_dh_derive_keys() now take a
-+	'void *memctx' as the 1st param.
-+
-+	dwc_modpow() now takes a 'void *memctx' as the 1st param.
-+
-+	dwc_alloc_notification_manager() now takes a 'void *memctx' as the
-+	1st param and a 'void *wkqctx' (for work queue allocation) as the 2nd
-+	param, and also now returns an integer value that is non-zero if
-+	allocation of its data structures or work queue fails.
-+
-+	dwc_register_notifier() now takes a 'void *memctx' as the 1st param.
-+
-+	dwc_memory_debug_start() now takes a 'void *mem_ctx' as the first
-+	param, and also now returns an integer value that is non-zero if
-+	allocation of its data structures fails.
-+
-+
-+
-+Other miscellaneous changes:
-+
-+The DEBUG_MEMORY and DEBUG_REGS #define's have been renamed to
-+DWC_DEBUG_MEMORY and DWC_DEBUG_REGS.
-+
-+The following #define's have been added to allow selectively compiling library
-+features:
-+
-+	DWC_CCLIB
-+	DWC_CRYPTOLIB
-+	DWC_NOTIFYLIB
-+	DWC_UTFLIB
-+
-+A DWC_LIBMODULE #define has also been added. If this is not defined, then the
-+module code in dwc_common_linux.c is not compiled in. This allows linking the
-+library code directly into a driver module, instead of as a standalone module.

-+ * This file defines linked list operations.  It is derived from BSD with

-+ */
-+
-+/*
-+ * This file defines five types of data structures: singly-linked lists,
-+ * lists, simple queues, tail queues, and circular queues.
-+ *
-+ *
-+ * A singly-linked list is headed by a single forward pointer. The elements
-+ * are singly linked for minimum space and pointer manipulation overhead at
-+ * the expense of O(n) removal for arbitrary elements. New elements can be
-+ * added to the list after an existing element or at the head of the list.
-+ * Elements being removed from the head of the list should use the explicit
-+ * macro for this purpose for optimum efficiency. A singly-linked list may
-+ * only be traversed in the forward direction.  Singly-linked lists are ideal
-+ * for applications with large datasets and few or no removals or for
-+ * implementing a LIFO queue.
-+ *
-+ * A list is headed by a single forward pointer (or an array of forward
-+ * pointers for a hash table header). The elements are doubly linked
-+ * so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before
-+ * or after an existing element or at the head of the list. A list
-+ * may only be traversed in the forward direction.
-+ *
-+ * A simple queue is headed by a pair of pointers, one the head of the
-+ * list and the other to the tail of the list. The elements are singly
-+ * linked to save space, so elements can only be removed from the
-+ * head of the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the
-+ * list. A simple queue may only be traversed in the forward direction.
-+ *
-+ * A tail queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or
-+ * after an existing element, at the head of the list, or at the end of
-+ * the list. A tail queue may be traversed in either direction.
-+ *
-+ * A circle queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the list.
-+ * A circle queue may be traversed in either direction, but has a more
-+ * complex end of list detection.
-+ *
-+ * For details on the use of these macros, see the queue(3) manual page.

-+/** @file
-+ *
-+ * A simple implementation of the Observer pattern.  Any "module" can
-+ * register as an observer or notifier.  The notion of "module" is abstract and
-+ * can mean anything used to identify either an observer or notifier.  Usually
-+ * it will be a pointer to a data structure which contains some state, ie an
-+ * object.
-+ *
-+ * Before any notifiers can be added, the global notification manager must be
-+ * brought up with dwc_alloc_notification_manager().
-+ * dwc_free_notification_manager() will bring it down and free all resources.
-+ * These would typically be called upon module load and unload.  The
-+ * notification manager is a single global instance that handles all registered
-+ * observable modules and observers so this should be done only once.
-+ *
-+ * A module can be observable by using Notifications to publicize some general
-+ * information about it's state or operation.  It does not care who listens, or
-+ * even if anyone listens, or what they do with the information.  The observable
-+ * modules do not need to know any information about it's observers or their
-+ * interface, or their state or data.
-+ *
-+ * Any module can register to emit Notifications.  It should publish a list of
-+ * notifications that it can emit and their behavior, such as when they will get
-+ * triggered, and what information will be provided to the observer.  Then it
-+ * should register itself as an observable module. See dwc_register_notifier().
-+ *
-+ * Any module can observe any observable, registered module, provided it has a
-+ * handle to the other module and knows what notifications to observe.  See
-+ * dwc_add_observer().
-+ *
-+ * A function of type dwc_notifier_callback_t is called whenever a notification
-+ * is triggered with one or more observers observing it.  This function is
-+ * called in it's own process so it may sleep or block if needed.  It is
-+ * guaranteed to be called sometime after the notification has occurred and will
-+ * be called once per each time the notification is triggered.  It will NOT be
-+ * called in the same process context used to trigger the notification.
-+ *
-+ * @section Limitiations
-+ *
-+ * Keep in mind that Notifications that can be triggered in rapid sucession may
-+ * schedule too many processes too handle.  Be aware of this limitation when
-+ * designing to use notifications, and only add notifications for appropriate
-+ * observable information.
-+ *
-+ * Also Notification callbacks are not synchronous.  If you need to synchronize
-+ * the behavior between module/observer you must use other means.  And perhaps
-+ * that will mean Notifications are not the proper solution.

-+/* @mainpage DWC Portability and Common Library
-+ *
-+ * This is the documentation for the DWC Portability and Common Library.
-+ *
-+ * @section intro Introduction
-+ *
-+ * The DWC Portability library consists of wrapper calls and data structures to
-+ * all low-level functions which are typically provided by the OS.  The WUDEV
-+ * driver uses only these functions.  In order to port the WUDEV driver, only
-+ * the functions in this library need to be re-implemented, with the same
-+ * behavior as documented here.
-+ *
-+ * The Common library consists of higher level functions, which rely only on
-+ * calling the functions from the DWC Portability library.  These common
-+ * routines are shared across modules.  Some of the common libraries need to be
-+ * used directly by the driver programmer when porting WUDEV.  Such as the
-+ * parameter and notification libraries.
-+ *
-+ * @section low Portability Library OS Wrapper Functions
-+ *
-+ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
-+ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC().  All of
-+ * these functions are included in the dwc_os.h file.
-+ *
-+ * There are many functions here covering a wide array of OS services.  Please
-+ * see dwc_os.h for details, and implementation notes for each function.
-+ *
-+ * @section common Common Library Functions
-+ *
-+ * Any function starting with dwc and in all lowercase is a common library
-+ * routine.  These functions have a portable implementation and do not need to
-+ * be reimplemented when porting.  The common routines can be used by any
-+ * driver, and some must be used by the end user to control the drivers.  For
-+ * example, you must use the Parameter common library in order to set the
-+ * parameters in the WUDEV module.
-+ *
-+ * The common libraries consist of the following:
-+ *
-+ * - Connection Contexts - Used internally and can be used by end-user.  See dwc_cc.h
-+ * - Parameters - Used internally and can be used by end-user.  See dwc_params.h
-+ * - Notifications - Used internally and can be used by end-user.  See dwc_notifier.h
-+ * - Lists - Used internally and can be used by end-user.  See dwc_list.h
-+ * - Memory Debugging - Used internally and can be used by end-user.  See dwc_os.h
-+ * - Modpow - Used internally only.  See dwc_modpow.h
-+ * - DH - Used internally only.  See dwc_dh.h
-+ * - Crypto - Used internally only.  See dwc_crypto.h
-+ *
-+ *
-+ * @section prereq Prerequistes For dwc_os.h
-+ * @subsection types Data Types
-+ *
-+ * The dwc_os.h file assumes that several low-level data types are pre defined for the
-+ * compilation environment.  These data types are:
-+ *
-+ * - uint8_t - unsigned 8-bit data type
-+ * - int8_t - signed 8-bit data type
-+ * - uint16_t - unsigned 16-bit data type
-+ * - int16_t - signed 16-bit data type
-+ * - uint32_t - unsigned 32-bit data type
-+ * - int32_t - signed 32-bit data type
-+ * - uint64_t - unsigned 64-bit data type
-+ * - int64_t - signed 64-bit data type
-+ *
-+ * Ensure that these are defined before using dwc_os.h.  The easiest way to do
-+ * that is to modify the top of the file to include the appropriate header.
-+ * This is already done for the Linux environment.  If the DWC_LINUX macro is
-+ * defined, the correct header will be added.  A standard header <stdint.h> is
-+ * also used for environments where standard C headers are available.
-+ *
-+ * @subsection stdarg Variable Arguments
-+ *
-+ * Variable arguments are provided by a standard C header <stdarg.h>.  it is
-+ * available in Both the Linux and ANSI C enviornment.  An equivalent must be
-+ * provided in your enviornment in order to use dwc_os.h with the debug and
-+ * tracing message functionality.
-+ *
-+ * @subsection thread Threading
-+ *
-+ * WUDEV Core must be run on an operating system that provides for multiple
-+ * threads/processes.  Threading can be implemented in many ways, even in
-+ * embedded systems without an operating system.  At the bare minimum, the
-+ * system should be able to start any number of processes at any time to handle
-+ * special work.  It need not be a pre-emptive system.  Process context can
-+ * change upon a call to a blocking function.  The hardware interrupt context
-+ * that calls the module's ISR() function must be differentiable from process
-+ * context, even if your processes are impemented via a hardware interrupt.
-+ * Further locking mechanism between process must exist (or be implemented), and
-+ * process context must have a way to disable interrupts for a period of time to
-+ * lock them out.  If all of this exists, the functions in dwc_os.h related to
-+ * threading should be able to be implemented with the defined behavior.
-+ *

-+ * Gadget Zero only needs two bulk endpoints, and is an example of how you
-+ * can write a hardware-agnostic gadget driver running inside a USB device.
-+ *
-+ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
-+ * affect most of the driver.
-+ *
-+ * Use it with the Linux host/master side "usbtest" driver to get a basic
-+ * functional test of your device-side usb stack, or with "usb-skeleton".
-+ *
-+ * It supports two similar configurations.  One sinks whatever the usb host
-+ * writes, and in return sources zeroes.  The other loops whatever the host
-+ * writes back, so the host can read it.  Module options include:
-+ *
-+ *   buflen=N		default N=4096, buffer size used
-+ *   qlen=N		default N=32, how many buffers in the loopback queue
-+ *   loopdefault	default false, list loopback config first
-+ *
-+ * Many drivers will only have one configuration, letting them be much
-+ * simpler if they also don't support high speed operation (like this
-+ * driver does).

-+ * The Core Interface Layer provides basic services for accessing and
-+ * managing the DWC_otg hardware. These services are used by both the
-+ * Host Controller Driver and the Peripheral Controller Driver.
-+ *
-+ * The CIL manages the memory map for the core so that the HCD and PCD
-+ * don't have to do this separately. It also handles basic tasks like
-+ * reading/writing the registers and data FIFOs in the controller.
-+ * Some of the data access functions provide encapsulation of several
-+ * operations required to perform a task, such as writing multiple
-+ * registers to start a transfer. Finally, the CIL performs basic
-+ * services that are not specific to either the host or device modes
-+ * of operation. These services include management of the OTG Host
-+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
-+ * Diagnostic API is also provided to allow testing of the controller
-+ * hardware.
-+ *
-+ * The Core Interface Layer has the following requirements:
-+ * - Provides basic controller operations.
-+ * - Minimal use of OS services.
-+ * - The OS services used will be abstracted by using inline functions
-+ *	 or macros.

-+/** @file
-+ * The dwc_otg_driver module provides the initialization and cleanup entry
-+ * points for the DWC_otg driver. This module will be dynamically installed
-+ * after Linux is booted using the insmod command. When the module is
-+ * installed, the dwc_otg_driver_init function is called. When the module is
-+ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
-+ *
-+ * This module also defines a data structure for the dwc_otg_driver, which is
-+ * used in conjunction with the standard ARM lm_device structure. These
-+ * structures allow the OTG driver to comply with the standard Linux driver
-+ * model in which devices and drivers are registered with a bus driver. This
-+ * has the benefit that Linux can expose attributes of the driver and device
-+ * in its special sysfs file system. Users can then read or write files in
-+ * this file system to perform diagnostics on the driver components or the
-+ * device.

-+ * This FIQ implements functionality that performs split transactions on
-+ * the dwc_otg hardware without any outside intervention. A split transaction
-+ * is "queued" by nominating a specific host channel to perform the entirety
-+ * of a split transaction. This FIQ will then perform the microframe-precise
-+ * scheduling required in each phase of the transaction until completion.
-+ *
-+ * The FIQ functionality is glued into the Synopsys driver via the entry point
-+ * in the FSM enqueue function, and at the exit point in handling a HC interrupt
-+ * for a FSM-enabled channel.
-+ *
-+ * NB: Large parts of this implementation have architecture-specific code.
-+ * For porting this functionality to other ARM machines, the minimum is required:
-+ * - An interrupt controller allowing the top-level dwc USB interrupt to be routed
-+ *   to the FIQ
-+ * - A method of forcing a software generated interrupt from FIQ mode that then
-+ *   triggers an IRQ entry (with the dwc USB handler called by this IRQ number)
-+ * - Guaranteed interrupt routing such that both the FIQ and SGI occur on the same
-+ *   processor core - there is no locking between the FIQ and IRQ (aside from
-+ *   local_fiq_disable)

-+ * The application interfaces with the HS OTG core by reading from and
-+ * writing to the Control and Status Register (CSR) space through the
-+ * AHB Slave interface. These registers are 32 bits wide, and the
-+ * addresses are 32-bit-block aligned.
-+ * CSRs are classified as follows:
-+ * - Core Global Registers
-+ * - Device Mode Registers
-+ * - Device Global Registers
-+ * - Device Endpoint Specific Registers
-+ * - Host Mode Registers
-+ * - Host Global Registers
-+ * - Host Port CSRs
-+ * - Host Channel Specific Registers
-+ *
-+ * Only the Core Global registers can be accessed in both Device and
-+ * Host modes. When the HS OTG core is operating in one mode, either
-+ * Device or Host, the application must not access registers from the
-+ * other mode. When the core switches from one mode to another, the
-+ * registers in the new mode of operation must be reprogrammed as they

-bcm2708_fb : Implement blanking support using the mailbox property interface
-
-bcm2708_fb: Add pan and vsync controls
-
-bcm2708_fb: DMA acceleration for fb_copyarea
-
-Based on http://www.raspberrypi.org/phpBB3/viewtopic.php?p=62425#p62425
-Also used Simon's dmaer_master module as a reference for tweaking DMA
-settings for better performance.
-
-For now busylooping only. IRQ support might be added later.
-With non-overclocked Raspberry Pi, the performance is ~360 MB/s
-for simple copy or ~260 MB/s for two-pass copy (used when dragging
-windows to the right).
-
-In the case of using DMA channel 0, the performance improves
-to ~440 MB/s.
-
-For comparison, VFP optimized CPU copy can only do ~114 MB/s in
-the same conditions (hindered by reading uncached source buffer).

-bcm2708_fb: report number of dma copies
-
-Add a counter (exported via debugfs) reporting the
-number of dma copies that the framebuffer driver
-has done, in order to help evaluate different
-optimization strategies.
-

-
-bcm2708_fb: use IRQ for DMA copies
-
-The copyarea ioctl() uses DMA to speed things along. This
-was busy-waiting for completion. This change supports using
-an interrupt instead for larger transfers. For small
-transfers, busy-waiting is still likely to be faster.

-correct bus address on ARCH_BCM2835.
-Use the new DMA legacy API header file.
-Including <mach/platform.h> is not necessary.

-From: Florian Meier <florian.meier@koalo.de>
-Date: Fri, 22 Nov 2013 14:22:53 +0100
-Subject: [PATCH] dmaengine: Add support for BCM2708
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add support for DMA controller of BCM2708 as used in the Raspberry Pi.
-Currently it only supports cyclic DMA.
-
-Signed-off-by: Florian Meier <florian.meier@koalo.de>
-
-dmaengine: expand functionality by supporting scatter/gather transfers sdhci-bcm2708 and dma.c: fix for LITE channels
-
-DMA: fix cyclic LITE length overflow bug
-
-dmaengine: bcm2708: Remove chancnt affectations
-
-Mirror bcm2835-dma.c commit 9eba5536a7434c69d8c185d4bd1c70734d92287d:
-chancnt is already filled by dma_async_device_register, which uses the channel
-list to know how much channels there is.
-
-Since it's already filled, we can safely remove it from the drivers' probe
-function.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: overwrite dreq only if it is not set
-
-dreq is set when the DMA channel is fetched from Device Tree.
-slave_id is set using dmaengine_slave_config().
-Only overwrite dreq with slave_id if it is not set.
-
-dreq/slave_id in the cyclic DMA case is not touched, because I don't
-have hardware to test with.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: do device registration in the board file
-
-Don't register the device in the driver. Do it in the board file.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: don't restrict DT support to ARCH_BCM2835
-
-Both ARCH_BCM2835 and ARCH_BCM270x are built with OF now.
-Add Device Tree support to the non ARCH_BCM2835 case.
-Use the same driver name regardless of architecture.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-BCM270x_DT: add bcm2835-dma entry
-
-Add Device Tree entry for bcm2835-dma.
-The entry doesn't contain any resources since they are handled
-by the arch/arm/mach-bcm270x/dma.c driver.
-In non-DT mode, don't add the device in the board file.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-bcm2708-dmaengine: Add debug options
-
-BCM270x: Add memory and irq resources to dmaengine device and DT
-
-Prepare for merging of the legacy DMA API arch driver dma.c
-with bcm2708-dmaengine by adding memory and irq resources both
-to platform file device and Device Tree node.
-Don't use BCM_DMAMAN_DRIVER_NAME so we don't have to include mach/dma.h
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.c
-
-Merge the legacy DMA API driver with bcm2708-dmaengine.
-This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
-driver is also needed).
-
-Changes to the dma.c code:
-- Use BIT() macro.
-- Cutdown some comments to one line.
-- Add mutex to vc_dmaman and use this, since the dev lock is locked
-  during probing of the engine part.
-- Add global g_dmaman variable since drvdata is used by the engine part.
-- Restructure for readability:
-  vc_dmaman_chan_alloc()
-  vc_dmaman_chan_free()
-  bcm_dma_chan_free()
-- Restructure bcm_dma_chan_alloc() to simplify error handling.
-- Use device irq resources instead of hardcoded bcm_dma_irqs table.
-- Remove dev_dmaman_register() and code it directly.
-- Remove dev_dmaman_deregister() and code it directly.
-- Simplify bcm_dmaman_probe() using devm_* functions.
-- Get dmachans from DT if available.
-- Keep 'dma.dmachans' module argument name for backwards compatibility.
-
-Make it available on ARCH_BCM2835 as well.

-dmaengine: bcm2708: set residue_granularity field
-
-bcm2708-dmaengine supports residue reporting at burst level
-but didn't report this via the residue_granularity field.
-
-Without this field set properly we get playback issues with I2S cards.
-
-dmaengine: bcm2708-dmaengine: Fix memory leak when stopping a running transfer
-
-bcm2708-dmaengine: Use more DMA channels (but not 12)
-
-1) Only the bcm2708_fb drivers uses the legacy DMA API, and
-it requires a BULK-capable channel, so all other types
-(FAST, NORMAL and LITE) can be made available to the regular
-DMA API.
-
-2) DMA channels 11-14 share an interrupt. The driver can't
-handle this, so don't use channels 12-14 (12 was used, probably
-because it appears to have an interrupt, but in reality that
-interrupt is for activity on ANY channel). This may explain
-a lockup encountered when running out of DMA channels.
-
-The combined effect of this patch is to leave 7 DMA channels
-available + channel 0 for bcm2708_fb via the legacy API.
-
-See: https://github.com/raspberrypi/linux/issues/1110
-     https://github.com/raspberrypi/linux/issues/1108
-
-dmaengine: bcm2708: Make legacy API available for bcm2835-dma
-
-bcm2708_fb uses the legacy DMA API, so in order to start using
-bcm2835-dma, bcm2835-dma has to support the legacy API. Make this
-possible by exporting bcm_dmaman_probe() and bcm_dmaman_remove().
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: Change DT compatible string
-
-Both bcm2835-dma and bcm2708-dmaengine have the same compatible string.
-So change compatible to "brcm,bcm2708-dma".
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: Remove driver but keep legacy API
-
-Dropping non-DT support means we don't need this driver,
-but we still need the legacy DMA API.

-From 5646c03db7e90b2eff7cec1679877ed2789ba3c9 Mon Sep 17 00:00:00 2001
-From: gellert <gellert@raspberrypi.org>
-Date: Fri, 15 Aug 2014 16:35:06 +0100
-Subject: [PATCH] MMC: added alternative MMC driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-mmc: Disable CMD23 transfers on all cards
-
-Pending wire-level investigation of these types of transfers
-and associated errors on bcm2835-mmc, disable for now. Fallback of
-CMD18/CMD25 transfers will be used automatically by the MMC layer.
-
-Reported/Tested-by: Gellert Weisz <gellert@raspberrypi.org>
-
-mmc: bcm2835-mmc: enable DT support for all architectures
-
-Both ARCH_BCM2835 and ARCH_BCM270x are built with OF now.
-Enable Device Tree support for all architectures.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-mmc: bcm2835-mmc: fix probe error handling
-
-Probe error handling is broken in several places.
-Simplify error handling by using device managed functions.
-Replace pr_{err,info} with dev_{err,info}.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-bcm2835-mmc: Add locks when accessing sdhost registers
-
-bcm2835-mmc: Add range of debug options for slowing things down
-
-bcm2835-mmc: Add option to disable some delays
-
-bcm2835-mmc: Add option to disable MMC_QUIRK_BLK_NO_CMD23
-
-bcm2835-mmc: Default to disabling MMC_QUIRK_BLK_NO_CMD23
-
-bcm2835-mmc: Adding overclocking option
-
-Allow a different clock speed to be substitued for a requested 50MHz.
-This option is exposed using the "overclock_50" DT parameter.
-Note that the mmc interface is restricted to EVEN integer divisions of
-250MHz, and the highest sensible option is 63 (250/4 = 62.5), the
-next being 125 (250/2) which is much too high.
-
-Use at your own risk.
-
-bcm2835-mmc: Round up the overclock, so 62 works for 62.5Mhz
-
-Also only warn once for each overclock setting.
-
-mmc: bcm2835-mmc: Make available on ARCH_BCM2835
-
-Make the bcm2835-mmc driver available for use on ARCH_BCM2835.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-BCM270x_DT: add bcm2835-mmc entry
-
-Add Device Tree entry for bcm2835-mmc.
-In non-DT mode, don't add the device in the board file.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>

-bcm2835-mmc: Don't overwrite MMC capabilities from DT

-From 81c93790b30530e11b744828d196d011a7dcaa5f Mon Sep 17 00:00:00 2001
-From: Phil Elwell <phil@raspberrypi.org>
-Date: Wed, 25 Mar 2015 17:49:47 +0000
-Subject: [PATCH] Adding bcm2835-sdhost driver, and an overlay to enable it
-
-BCM2835 has two SD card interfaces. This driver uses the other one.
-
-bcm2835-sdhost: Error handling fix, and code clarification
-
-bcm2835-sdhost: Adding overclocking option
-
-Allow a different clock speed to be substitued for a requested 50MHz.
-This option is exposed using the "overclock_50" DT parameter.
-Note that the sdhost interface is restricted to integer divisions of
-core_freq, and the highest sensible option for a core_freq of 250MHz
-is 84 (250/3 = 83.3MHz), the next being 125 (250/2) which is much too
-high.
-
-Use at your own risk.
-
-bcm2835-sdhost: Round up the overclock, so 62 works for 62.5Mhz
-
-Also only warn once for each overclock setting.
-
-bcm2835-sdhost: Improve error handling and recovery
-
-1) Expose the hw_reset method to the MMC framework, removing many
-   internal calls by the driver.
-
-2) Reduce overclock setting on error.
-
-3) Increase timeout to cope with high capacity cards.
-
-4) Add properties and parameters to control pio_limit and debug.
-
-5) Reduce messages at probe time.
-
-bcm2835-sdhost: Further improve overclock back-off
-
-bcm2835-sdhost: Clear HBLC for PIO mode
-
-Also update pio_limit default in overlay README.
-
-bcm2835-sdhost: Add the ERASE capability
-
-See: https://github.com/raspberrypi/linux/issues/1076
-
-bcm2835-sdhost: Ignore CRC7 for MMC CMD1
-
-It seems that the sdhost interface returns CRC7 errors for CMD1,
-which is the MMC-specific SEND_OP_COND. Returning these errors to
-the MMC layer causes a downward spiral, but ignoring them seems
-to be harmless.
-
-bcm2835-mmc/sdhost: Remove ARCH_BCM2835 differences
-
-The bcm2835-mmc driver (and -sdhost driver that copied from it)
-contains code to handle SDIO interrupts in a threaded interrupt
-handler rather than waking the MMC framework thread. The change
-follows a patch from Russell King that adds the facility as the
-preferred way of working.
-
-However, the new code path is only present in ARCH_BCM2835
-builds, which I have taken to be a way of testing the waters
-rather than making the change across the board; I can't see
-any technical reason why it wouldn't be enabled for MACH_BCM270X
-builds. So this patch standardises on the ARCH_BCM2835 code,
-removing the old code paths.
-
-bcm2835-sdhost: Don't log timeout errors unless debug=1
-
-The MMC card-discovery process generates timeouts. This is
-expected behaviour, so reporting it to the user serves no purpose.
-Suppress the reporting of timeout errors unless the debug flag
-is on.

-Subject: [PATCH] cma: Add vc_cma driver to enable use of CMA
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Signed-off-by: popcornmix <popcornmix@gmail.com>
-
-vc_cma: Make the vc_cma area the default contiguous DMA area
-
-vc_cma: Provide empty functions when module is not built
-
-Providing empty functions saves the users from guarding the
-function call with an #if clause.
-Move __init markings from prototypes to functions.

-From: popcornmix <popcornmix@gmail.com>
-Date: Mon, 26 Mar 2012 22:15:50 +0100
-Subject: [PATCH] bcm2708: alsa sound driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Signed-off-by: popcornmix <popcornmix@gmail.com>
-
-alsa: add mmap support and some cleanups to bcm2835 ALSA driver
-
-snd-bcm2835: Add support for spdif/hdmi passthrough
-
-This adds a dedicated subdevice which can be used for passthrough of non-audio
-formats (ie encoded a52) through the hdmi audio link. In addition to this
-driver extension an appropriate card config is required to make alsa-lib
-support the AES parameters for this device.
-
-snd-bcm2708: Add mutex, improve logging
-
-Fix for ALSA driver crash
-
-Avoids an issue when closing and opening vchiq where a message can arrive before service handle has been written
-
-alsa: reduce severity of expected warning message
-
-snd-bcm2708: Fix dmesg spam for non-error case
-
-alsa: Ensure mutexes are released through error paths
-
-alsa: Make interrupted close paths quieter
-
-BCM270x: Add onboard sound device to Device Tree
-
-Add Device Tree support to alsa driver.
-Add device to Device Tree.
-Don't add platform devices when booting in DT mode.

-VCHIQ: Make service closure fully synchronous (drv)
-
-This is one half of a two-part patch, the other half of which is to
-the vchiq_lib user library. With these patches, calls to
-vchiq_close_service and vchiq_remove_service won't return until any
-associated callbacks have been delivered to the callback thread.
-
-VCHIQ: Add per-service tracing
-
-The new service option VCHIQ_SERVICE_OPTION_TRACE is a boolean that
-toggles tracing for the specified service.
-
-This commit also introduces vchi_service_set_option and the associated
-option VCHI_SERVICE_OPTION_TRACE.
-
-vchiq: Make the synchronous-CLOSE logic more tolerant
-
-vchiq: Move logging control into debugfs
-
-vchiq: Take care of a corner case tickled by VCSM
-
-Closing a connection that isn't fully open requires care, since one
-side does not know the other side's port number. Code was present to
-handle the case where a CLOSE is sent immediately after an OPEN, i.e.
-before the OPENACK has been received, but this was incorrectly being
-used when an OPEN from a client using port 0 was rejected.
-
-(In the observed failure, the host was attempting to use the VCSM
-service, which isn't present in the 'cutdown' firmware. The failure
-was intermittent because sometimes the keepalive service would
-grab port 0.)
-
-This case can be distinguished because the client's remoteport will
-still be VCHIQ_PORT_FREE, and the srvstate will be OPENING. Either
-condition is sufficient to differentiate it from the special case
-described above.
-
-vchiq: Avoid high load when blocked and unkillable
-
-vchiq: Include SIGSTOP and SIGCONT in list of signals not-masked by vchiq to allow gdb to work
-
-vchiq_arm: Complete support for SYNCHRONOUS mode
-
-vchiq: Remove inline from suspend/resume
-
-vchiq: Allocation does not need to be atomic
-
-vchiq: Fix wrong condition check
-
-The log level is checked from within the log call. Remove the check in the call.

-
-bcm2708: vchiq: Add Device Tree support
-
-Turn vchiq into a driver and stop hardcoding resources.
-Use devm_* functions in probe path to simplify cleanup.
-A global variable is used to hold the register address. This is done
-to keep this patch as small as possible.
-Also make available on ARCH_BCM2835.
-Based on work by Lubomir Rintel.

-vchiq: Change logging level for inbound data
-
-vchiq_arm: Two cacheing fixes
-
-1) Make fragment size vary with cache line size
-Without this patch, non-cache-line-aligned transfers may corrupt
-(or be corrupted by) adjacent data structures.
-
-Both ARM and VC need to be updated to enable this feature. This is
-ensured by having the loader apply a new DT parameter -
-cache-line-size. The existence of this parameter guarantees that the
-kernel is capable, and the parameter will only be modified from the
-safe default if the loader is capable.
-
-2) Flush/invalidate vmalloc'd memory, and invalidate after reads
-
-vchiq: fix NULL pointer dereference when closing driver
-
-The following code run as root will cause a null pointer dereference oops:
-
-        int fd = open("/dev/vc-cma", O_RDONLY);
-        if (fd < 0)
-                err(1, "open failed");
-        (void)close(fd);

-
-..the fix is to ensure that we have actually initialized the queue before we attempt
-to push any items onto it.  This occurs if we do an open() followed by a close() without
-any activity in between.

-+** Functions to modify the state variables;
-+**	set_suspend_state
-+**	set_resume_state
-+**
-+** There are more state variables than we might like, so ensure they remain in
-+** step.  Suspend and resume state are maintained separately, since most of
-+** these state machines can operate independently.  However, there are a few
-+** states where state transitions in one state machine cause a reset to the
-+** other state machine.  In addition, there are some completion events which
-+** need to occur on state machine reset and end-state(s), so these are also
-+** dealt with in these functions.
-+**
-+** In all states we set the state variable according to the input, but in some
-+** cases we perform additional steps outlined below;
-+**
-+** VC_SUSPEND_IDLE - Initialise the suspend completion at the same time.
-+**			The suspend completion is completed after any suspend
-+**			attempt.  When we reset the state machine we also reset
-+**			the completion.  This reset occurs when videocore is
-+**			resumed, and also if we initiate suspend after a suspend
-+**			failure.
-+**
-+** VC_SUSPEND_IN_PROGRESS - This state is considered the point of no return for
-+**			suspend - ie from this point on we must try to suspend
-+**			before resuming can occur.  We therefore also reset the
-+**			resume state machine to VC_RESUME_IDLE in this state.
-+**
-+** VC_SUSPEND_SUSPENDED - Suspend has completed successfully. Also call
-+**			complete_all on the suspend completion to notify
-+**			anything waiting for suspend to happen.
-+**
-+** VC_SUSPEND_REJECTED - Videocore rejected suspend. Videocore will also
-+**			initiate resume, so no need to alter resume state.
-+**			We call complete_all on the suspend completion to notify
-+**			of suspend rejection.
-+**
-+** VC_SUSPEND_FAILED - We failed to initiate videocore suspend.  We notify the
-+**			suspend completion and reset the resume state machine.
-+**
-+** VC_RESUME_IDLE - Initialise the resume completion at the same time.  The
-+**			resume completion is in it's 'done' state whenever
-+**			videcore is running.  Therfore, the VC_RESUME_IDLE state
-+**			implies that videocore is suspended.
-+**			Hence, any thread which needs to wait until videocore is
-+**			running can wait on this completion - it will only block
-+**			if videocore is suspended.
-+**
-+** VC_RESUME_RESUMED - Resume has completed successfully.  Videocore is running.
-+**			Call complete_all on the resume completion to unblock
-+**			any threads waiting for resume.	 Also reset the suspend
-+**			state machine to it's idle state.
-+**
-+** VC_RESUME_FAILED - Currently unused - no mechanism to fail resume exists.

-Date: Tue, 22 Jul 2014 15:41:04 +0100
-Subject: [PATCH] vcsm: VideoCore shared memory service for BCM2835
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add experimental support for the VideoCore shared memory service.
-This allows user processes to allocate memory from VideoCore's
-GPU relocatable heap and mmap the buffers. Additionally, the memory
-handles can passed to other VideoCore services such as MMAL, OpenMax
-and DispmanX
-
-TODO
-* This driver was originally released for BCM28155 which has a different
-  cache architecture to BCM2835. Consequently, in this release only
-  uncached mappings are supported. However, there's no fundamental
-  reason which cached mappings cannot be support or BCM2835
-* More refactoring is required to remove the typedefs.
-* Re-enable the some of the commented out debug-fs statistics which were
-  disabled when migrating code from proc-fs.
-* There's a lot of code to support sharing of VCSM in order to support
-  Android. This could probably done more cleanly or perhaps just
-  removed.

-+* BCM2835 SMI NAND flash
-+
-+This driver is a shim between the BCM2835 SMI driver (SMI is a peripheral for
-+talking to parallel register interfaces) and Linux's MTD layer.
-+
-+Required properties:
-+- compatible: "brcm,bcm2835-smi-nand"
-+- status: "okay"
-+
-+Optional properties:
-+- partition@n, where n is an integer from a consecutive sequence starting at 0
-+	- Difficult to store partition table on NAND device - normally put it
-+	in the source code, kernel bootparams, or device tree (the best way!)
-+	- Sub-properties:
-+		- label: the partition name, as shown by mtdinfo /dev/mtd*
-+		- reg: the size and offset of this partition.
-+		- (optional) read-only: an empty property flagging as read only
-+
-+Example:
-+
-+nand: flash@0 {
-+	compatible = "brcm,bcm2835-smi-nand";
-+	status = "okay";
-+
-+	partition@0 {
-+		label = "stage2";
-+		// 128k
-+		reg = <0 0x20000>;
-+		read-only;
-+	};
-+	partition@1 {
-+		label = "firmware";
-+		// 16M
-+		reg = <0x20000 0x1000000>;
-+		read-only;
-+	};
-+	partition@2 {
-+		label = "root";
-+		// 2G
-+		reg = <0x1020000 0x80000000>;
-+	};

-From e39854b38284178a8c63b4dc160d5883c2ce0a42 Mon Sep 17 00:00:00 2001
-From: Aron Szabo <aron@aron.ws>
-Date: Sat, 16 Jun 2012 12:15:55 +0200
-Subject: [PATCH] lirc: added support for RaspberryPi GPIO
-
-lirc_rpi: Use read_current_timer to determine transmitter delay. Thanks to jjmz and others
-See: https://github.com/raspberrypi/linux/issues/525
-
-lirc: Remove restriction on gpio pins that can be used with lirc
-
-Compute Module, for example could use different pins
-
-lirc_rpi: Add parameter to specify input pin pull
-
-Depending on the connected IR circuitry it might be desirable to change the
-gpios internal pull from it pull-down default behaviour. Add a module
-parameter to allow the user to set it explicitly.
-
-Signed-off-by: Julian Scheel <julian@jusst.de>
-
-lirc-rpi: Use the higher-level irq control functions
-
-This module used to access the irq_chip methods of the
-gpio controller directly, rather than going through the
-standard enable_irq/irq_set_irq_type functions. This
-caused problems on pinctrl-bcm2835 which only implements
-the irq_enable/disable methods and not irq_unmask/mask.
-
-lirc-rpi: Correct the interrupt usage
-
-1) Correct the use of enable_irq (i.e. don't call it so often)
-2) Correct the shutdown sequence.
-3) Avoid a bcm2708_gpio driver quirk by setting the irq flags earlier
-
-lirc-rpi: use getnstimeofday instead of read_current_timer
-
-read_current_timer isn't guaranteed to return values in
-microseconds, and indeed it doesn't on a Pi2.
-
-Issue: linux#827
-
-lirc-rpi: Add device tree support, and a suitable overlay
-
-The overlay supports DT parameters that match the old module
-parameters, except that gpio_in_pull should be set using the
-strings "up", "down" or "off".
-
-lirc-rpi: Also support pinctrl-bcm2835 in non-DT mode

-i2c-bcm2708: fixed baudrate
-
-Fixed issue where the wrong CDIV value was set for baudrates below 3815 Hz (for 250MHz bus clock).
-In that case the computed CDIV value was more than 0xffff. However the CDIV register width is only 16 bits.
-This resulted in incorrect setting of CDIV and higher baudrate than intended.
-Example: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0x1704 -> 42430Hz
-After correction: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0xffff -> 3815Hz
-The correct baudrate is shown in the log after the cdiv > 0xffff correction.
-
-Perform I2C combined transactions when possible
-
-Perform I2C combined transactions whenever possible, within the
-restrictions of the Broadcomm Serial Controller.
-
-Disable DONE interrupt during TA poll
-
-Prevent interrupt from being triggered if poll is missed and transfer
-starts and finishes.
-
-i2c: Make combined transactions optional and disabled by default
-
-i2c: bcm2708: add device tree support
-
-Add DT support to driver and add to .dtsi file.
-Setup pins in .dts file.
-i2c is disabled by default.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-bcm2708: don't register i2c controllers when using DT
-
-The devices for the i2c controllers are in the Device Tree.
-Only register devices when not using DT.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-I2C: Only register the I2C device for the current board revision
-
-i2c_bcm2708: Fix clock reference counting
-
-Fix grabbing lock from atomic context in i2c driver
-
-2 main changes:
-- check for timeouts in the bcm2708_bsc_setup function as indicated by this comment:
-      /* poll for transfer start bit (should only take 1-20 polls) */
-  This implies that the setup function can now fail so account for this everywhere it's called
-- Removed the clk_get_rate call from inside the setup function as it locks a mutex and that's not ok since we call it from under a spin lock.
-
-i2c-bcm2708: When using DT, leave the GPIO setup to pinctrl
-
-i2c-bcm2708: Increase timeouts to allow larger transfers
-
-Use the timeout value provided by the I2C_TIMEOUT ioctl when waiting
-for completion. The default timeout is 1 second.
-
-See: https://github.com/raspberrypi/linux/issues/260
-
-i2c-bcm2708/BCM270X_DT: Add support for I2C2
-
-The third I2C bus (I2C2) is normally reserved for HDMI use. Careless
-use of this bus can break an attached display - use with caution.
-
-It is recommended to disable accesses by VideoCore by setting
-hdmi_ignore_edid=1 or hdmi_edid_file=1 in config.txt.
-
-The interface is disabled by default - enable using the
-i2c2_iknowwhatimdoing DT parameter.
-
-bcm2708-spi: Don't use static pin configuration with DT
-
-Also remove superfluous error checking - the SPI framework ensures the
-validity of the chip_select value.
-
-i2c-bcm2708: Remove non-DT support

-V4L2: Fixes from 6by9
-
-V4L2: Fix EV values. Add manual shutter speed control
-
-V4L2 EV values should be in units of 1/1000. Corrected.
-Add support for V4L2_CID_EXPOSURE_ABSOLUTE which should
-give manual shutter control. Requires manual exposure mode
-to be selected first.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Correct JPEG Q-factor range
-
-Should be 1-100, not 0-100
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix issue of driver jamming if STREAMON failed.
-
-Fix issue where the driver was left in a partially enabled
-state if STREAMON failed, and would then reject many IOCTLs
-as it thought it was streaming.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix ISO controls.
-
-Driver was passing the index to the GPU, and not the desired
-ISO value.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Add flicker avoidance controls
-
-Add support for V4L2_CID_POWER_LINE_FREQUENCY to set flicker
-avoidance frequencies.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Add support for frame rate control.
-
-Add support for frame rate (or time per frame as V4L2
-inverts it) control via s_parm.

-
-V4L2: Add support for inline H264 headers
-
-Add support for V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER
-to control H264 inline headers.
-Requires firmware fix to work correctly, otherwise format
-has to be set to H264 before this parameter is set.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix JPEG timestamp issue
-
-JPEG images were coming through from the GPU with timestamp
-of 0. Detect this and give current system time instead
-of some invalid value.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix issue when switching down JPEG resolution.
-
-JPEG buffer size calculation is based on input resolution.
-Input resolution was being configured after output port
-format. Caused failures if switching from one JPEG resolution
-to a smaller one.
-

-
-V4L2: Add option to disable enum_framesizes.
-
-Gstreamer's handling of a driver that advertises
-V4L2_FRMSIZE_TYPE_STEPWISE to define the supported
-resolutions is broken. See bug
-https://bugzilla.gnome.org/show_bug.cgi?id=726521
-
-Optional parameter of gst_v4l2src_is_broken added.
-If non-zero, the driver claims not to support that
-ioctl, and gstreamer should be happy again (it
-guesses a set of defaults for itself).
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Add support for more image formats
-
-Adds YVU420 (YV12), YVU420SP (NV21), and BGR888.

-
-V4L2: Extend range for V4L2_CID_MPEG_VIDEO_H264_I_PERIOD
-
-Request to extend the range from the fairly arbitrary
-1000 frames (33 seconds at 30fps). Extend out to the
-max range supported (int32 value).
-Also allow 0, which is handled by the codec as only
-send an I-frame on the first frame and never again.
-There may be an exception if it detects a significant
-scene change, but there's no easy way around that.

-bcm2835-camera: stop_streaming now has a void return
-
-BCM2835-V4L2: Fix compliance test failures
-
-VIDIOC_TRY_FMT and VIDIOC_S_FMT tests were faling due
-to reporting V4L2_COLORSPACE_JPEG when the colour
-format wasn't V4L2_PIX_FMT_JPEG.
-Now reports V4L2_COLORSPACE_SMPTE170M for YUV formats.
-
-bcm2835 camera planar/packed stride length
-
-Added a field to the mmal_fmt struct used to compute the bytes per line
-when using a particular format. This results in the correct stride being
-calculated even when the format is planar.

-[drivers/media/platform/bcm2835/controls.c:854]: (error) Possible null
-  pointer dereference: scene

-From 3703cda20110756a6531a570a4e52b2b42d99bf9 Mon Sep 17 00:00:00 2001
-From: Phil Elwell <phil@raspberrypi.org>
-Date: Mon, 11 May 2015 09:00:42 +0100
-Subject: [PATCH] scripts: Add mkknlimg and knlinfo scripts from tools repo
-
-The Raspberry Pi firmware looks for a trailer on the kernel image to
-determine whether it was compiled with Device Tree support enabled.
-If the firmware finds a kernel without this trailer, or which has a
-trailer indicating that it isn't DT-capable, it disables DT support
-and reverts to using ATAGs.
-
-The mkknlimg utility adds that trailer, having first analysed the
-image to look for signs of DT support and the kernel version string.
-
-knlinfo displays the contents of the trailer in the given kernel image.
-
-scripts/mkknlimg: Add support for ARCH_BCM2835
-
-Add a new trailer field indicating whether this is an ARCH_BCM2835
-build, as opposed to MACH_BCM2708/9. If the loader finds this flag
-is set it changes the default base dtb file name from bcm270x...
-to bcm283y...
-
-Also update knlinfo to show the status of the field.
-
-scripts/mkknlimg: Improve ARCH_BCM2835 detection
-
-The board support code contains sufficient strings to be able to
-distinguish 2708 vs. 2835 builds, so remove the check for
-bcm2835-pm-wdt which could exist in either.
-
-Also, since the canned configuration is no longer built in (it's
-a module), remove the config string checking.
-
-See: https://github.com/raspberrypi/linux/issues/1157

-Use dts-dirs feature for overlays.
-
-The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
-
-Using this fixes the install_dtbs target, which previously did not install the overlays.
-
-BCM270X_DT: configure I2S DMA channels
-
-Signed-off-by: Matthias Reichl <hias@horus.com>
-
-BCM270X_DT: switch to bcm2835-i2s
-
-I2S soundcard drivers with proper devicetree support (i.e. not linking
-to the cpu_dai/platform via name but to cpu/platform via of_node)
-will work out of the box without any modifications.
-
-When the kernel is compiled without devicetree support the platform
-code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
-will link to it via name, as before.

-
-SDIO-overlay: add poll_once-boolean parameter
-
-Add paramter to toggle sdio-device-polling
-done every second or once at boot-time.

-
-BCM270X_DT: Make mmc overlay compatible with current firmware
-
-The original DT overlay logic followed a merge-then-patch procedure,
-i.e. parameters are applied to the loaded overlay before the overlay
-is merged into the base DTB. This sequence has been changed to
-patch-then-merge, in order to support parameterised node names, and
-to protect against bad overlays. As a result, overrides (parameters)
-must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
-
-mmc-overlay.dts (that switches back to the original mmc sdcard
-driver) is the only overlay violating that rule, and this patch
-fixes it.
-
-bcm270x_dt: Use the sdhost MMC controller by default
-
-The "mmc" overlay reverts to using the other controller.
-
-squash: Add cprman to dt
-
-BCM270X_DT: Use clk_core for I2C interfaces

-+Introduction
-+============
-+
-+This directory contains Device Tree overlays. Device Tree makes it possible
-+to support many hardware configurations with a single kernel and without the
-+need to explicitly load or blacklist kernel modules. Note that this isn't a
-+"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
-+are still configured by the board support code, but the intention is to
-+eventually reach that goal.
-+
-+On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
-+default, the Raspberry Pi kernel boots with device tree enabled. You can
-+completely disable DT usage (for now) by adding:
-+
-+    device_tree=
-+
-+to your config.txt, which should cause your Pi to revert to the old way of
-+doing things after a reboot.
-+
-+In /boot you will find a .dtb for each base platform. This describes the
-+hardware that is part of the Raspberry Pi board. The loader (start.elf and its
-+siblings) selects the .dtb file appropriate for the platform by name, and reads
-+it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
-+are disabled, but they can be enabled using Device Tree parameters:
-+
-+    dtparam=i2c=on,i2s=on,spi=on
-+
-+However, this shouldn't be necessary in many use cases because loading an
-+overlay that requires one of those interfaces will cause it to be enabled
-+automatically, and it is advisable to only enable interfaces if they are
-+needed.
-+
-+Configuring additional, optional hardware is done using Device Tree overlays
-+(see below).
-+
-+raspi-config
-+============
-+
-+The Advanced Options section of the raspi-config utility can enable and disable
-+Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
-+is possible to both enable an interface and blacklist the driver, if for some
-+reason you should want to defer the loading.
-+
-+Modules
-+=======
-+
-+As well as describing the hardware, Device Tree also gives enough information
-+to allow suitable driver modules to be located and loaded, with the corollary
-+that unneeded modules are not loaded. As a result it should be possible to
-+remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
-+have its contents deleted (or commented out).
-+
-+Using Overlays
-+==============
-+
-+Overlays are loaded using the "dtoverlay" directive. As an example, consider the
-+popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
-+pre-DT world this would be loaded from /etc/modules, with an explicit
-+"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
-+this becomes a line in config.txt:
-+
-+    dtoverlay=lirc-rpi
-+
-+This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By
-+default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
-+DT parameters:
-+
-+    dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
-+
-+Parameters always have default values, although in some cases (e.g. "w1-gpio")
-+it is necessary to provided multiple overlays in order to get the desired
-+behaviour. See the list of overlays below for a description of the parameters and their defaults.
-+
-+The Overlay and Parameter Reference

-+
-+        act_led_trigger          Choose which activity the LED tracks.
-+                                 Use "heartbeat" for a nice load indicator.
-+                                 (default "mmc")
-+
-+        act_led_activelow        Set to "on" to invert the sense of the LED
-+                                 (default "off")

-+                                 (in case you want to connect it to an external
-+                                 device)
-+                                 (default "16" on a non-Plus board, "47" on a

-+                                 Not available on Model A/B boards.
-+
-+        N.B. It is recommended to only enable those interfaces that are needed.
-+        Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
-+        interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
-+        Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
-+        interfaces i2c0 and i2c1. Use of the numeric variants is still possible
-+        but deprecated because the ARM/VC assignments differ between board
-+        revisions. The same board-specific mapping applies to i2c_baudrate,
-+        and the other i2c baudrate parameters.

-+Troubleshooting
-+===============
-+
-+If you are experiencing problems that you think are DT-related, enable DT
-+diagnostic output by adding this to /boot/config.txt:
-+
-+    dtdebug=on
-+
-+and rebooting. Then run:
-+
-+    sudo vcdbg log msg
-+
-+and look for relevant messages.
-+

-Subject: [PATCH] fbdev: add FBIOCOPYAREA ioctl
-
-Based on the patch authored by Ali Gholami Rudi at
-    https://lkml.org/lkml/2009/7/13/153
-
-Provide an ioctl for userspace applications, but only if this operation
-is hardware accelerated (otherwide it does not make any sense).

-Subject: [PATCH] Speed up console framebuffer imageblit function
-
-Especially on platforms with a slower CPU but a relatively high
-framebuffer fill bandwidth, like current ARM devices, the existing
-console monochrome imageblit function used to draw console text is
-suboptimal for common pixel depths such as 16bpp and 32bpp. The existing
-code is quite general and can deal with several pixel depths. By creating
-special case functions for 16bpp and 32bpp, by far the most common pixel
-formats used on modern systems, a significant speed-up is attained
-which can be readily felt on ARM-based devices like the Raspberry Pi
-and the Allwinner platform, but should help any platform using the
-fb layer.
-
-The special case functions allow constant folding, eliminating a number
-of instructions including divide operations, and allow the use of an
-unrolled loop, eliminating instructions with a variable shift size,
-reducing source memory access instructions, and eliminating excessive
-branching. These unrolled loops also allow much better code optimization
-by the C compiler. The code that selects which optimized variant is used
-is also simplified, eliminating integer divide instructions.
-
-The speed-up, measured by timing 'cat file.txt' in the console, varies
-between 40% and 70%, when testing on the Raspberry Pi and Allwinner
-ARM-based platforms, depending on font size and the pixel depth, with
-the greater benefit for 32bpp.

-Subject: [PATCH] ASoC: wm8804: Implement MCLK configuration options, add 32bit
- support WM8804 can run with PLL frequencies of 256xfs and 128xfs for most
- sample rates. At 192kHz only 128xfs is supported. The existing driver selects
- 128xfs automatically for some lower samples rates. By using an additional
- mclk_div divider, it is now possible to control the behaviour. This allows
- using 256xfs PLL frequency on all sample rates up to 96kHz. It should allow
- lower jitter and better signal quality. The behavior has to be controlled by
- the sound card driver, because some sample frequency share the same setting.
- e.g. 192kHz and 96kHz use 24.576MHz master clock. The only difference is the
- MCLK divider.
-
-This also added support for 32bit data.

-Subject: [PATCH] ASoC: BCM:Add support for HiFiBerry Digi. Driver is based on
- the patched WM8804 driver.
-
-Signed-off-by: Daniel Matuschek <daniel@matuschek.net>
-
-Add a parameter to turn off SPDIF output if no audio is playing
-
-This patch adds the paramater auto_shutdown_output to the kernel module.
-Default behaviour of the module is the same, but when auto_shutdown_output
-is set to 1, the SPDIF oputput will shutdown if no stream is playing.
-
-bugfix for 32kHz sample rate, was missing
-
-HiFiBerry Digi: set SPDIF status bits for sample rate
-
-The HiFiBerry Digi driver did not signal the sample rate in the SPDIF status bits.
-While this is optional, some DACs and receivers do not accept this signal. This patch
-adds the sample rate bits in the SPDIF status block.

-Subject: [PATCH] Add IQaudIO Sound Card support for Raspberry Pi
-
-Set a limit of 0dB on Digital Volume Control
-
-The main volume control in the PCM512x DAC has a range up to
-+24dB. This is dangerously loud and can potentially cause massive
-clipping in the output stages. Therefore this sets a sensible
-limit of 0dB for this control.

-From e45e0b8804ee1cf5ed841c021c82bc9f9a888ed3 Mon Sep 17 00:00:00 2001
-From: Daniel Matuschek <info@crazy-audio.com>
-Date: Mon, 4 Aug 2014 11:09:58 +0200
-Subject: [PATCH] Added driver for HiFiBerry Amp amplifier add-on board
-
-The driver contains a low-level hardware driver for the TAS5713 and the
-drivers for the Raspberry Pi I2S subsystem.
-
-TAS5713: return error if initialisation fails
-
-Existing TAS5713 driver logs errors during initialisation, but does not return
-an error code. Therefore even if initialisation fails, the driver will still be
-loaded, but won't work. This patch fixes this. I2C communication error will now
-reported correctly by a non-zero return code.
-
-HiFiBerry Amp: fix device-tree problems
-
-Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.

-Subject: [PATCH] BCM270x_DT: Add pwr_led, and the required "input" trigger
-
-The "input" trigger makes the associated GPIO an input.  This is to support
-the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
-
-N.B. pwr_led is not available on Model A or B boards.
-
-leds-gpio: Implement the brightness_get method
-
-The power LED uses some clever logic that means it is driven
-by a voltage measuring circuit when configured as input, otherwise
-it is driven by the GPIO output value. This patch wires up the
-brightness_get method for leds-gpio so that user-space can monitor
-the LED value via /sys/class/gpio/led1/brightness. Using the input
-trigger this returns an indication of the system power health,
-otherwise it is just whatever value the trigger has written most
-recently.
-
-See: https://github.com/raspberrypi/linux/issues/1064

-Subject: [PATCH] Improve __copy_to_user and __copy_from_user performance
-
-Provide a __copy_from_user that uses memcpy. On BCM2708, use
-optimised memcpy/memmove/memcmp/memset implementations.
-
-arch/arm: Add mmiocpy/set aliases for memcpy/set
-
-See: https://github.com/raspberrypi/linux/issues/1082

-Subject: [PATCH] gpio-poweroff: Allow it to work on Raspberry Pi
-
-The Raspberry Pi firmware manages the power-down and reboot
-process. To do this it installs a pm_power_off handler, causing
-the gpio-poweroff module to abort the probe function.
-
-This patch introduces a "force" DT property that overrides that
-behaviour, and also adds a DT overlay to enable and control it.

-Date: Wed, 11 Nov 2015 11:38:59 +0000
-Subject: [PATCH] scripts: Multi-platform support for mkknlimg and knlinfo
-
-The firmware uses tags in the kernel trailer to choose which dtb file
-to load. Current firmware loads bcm2835-*.dtb if the '283x' tag is true,
-otherwise it loads bcm270*.dtb. This scheme breaks if an image supports
-multiple platforms.
-
-This patch adds '270X' and '283X' tags to indicate support for RPi and
-upstream platforms, respectively. '283x' (note lower case 'x') is left
-for old firmware, and is only set if the image only supports upstream
-builds.

-Subject: [PATCH] drm/vc4: Add suport for 3D rendering using the V3D engine.
-
-This is a squash of the out-of-tree development series.  Since that
-series contained code from the first "get a demo triangle rendered
-using a hacked up driver using binary shader code" to "plug the last
-known security hole", it's hard to reconstruct a different series of
-incremental development that's mergeable without security holes
-throughout it.

-+ * We have an interrupt status register (V3D_INTCTL) which reports
-+ * interrupts, and where writing 1 bits clears those interrupts.
-+ * There are also a pair of interrupt registers
-+ * (V3D_INTENA/V3D_INTDIS) where writing a 1 to their bits enables or
-+ * disables that specific interrupt, and 0s written are ignored
-+ * (reading either one returns the set of enabled interrupts).
-+ *
-+ * When we take a render frame interrupt, we need to wake the
-+ * processes waiting for some frame to be done, and get the next frame
-+ * submitted ASAP (so the hardware doesn't sit idle when there's work
-+ * to do).
-+ *
-+ * When we take the binner out of memory interrupt, we need to
-+ * allocate some new memory and pass it to the binner so that the
-+ * current job can make progress.

-+ * DOC: Shader validator for VC4.
-+ *
-+ * The VC4 has no IOMMU between it and system memory.  So, a user with access
-+ * to execute shaders could escalate privilege by overwriting system memory
-+ * (using the VPM write address register in the general-purpose DMA mode) or
-+ * reading system memory it shouldn't (reading it as a texture, or uniform
-+ * data, or vertex data).
-+ *
-+ * This walks over a shader starting from some offset within a BO, ensuring
-+ * that its accesses are appropriately bounded, and recording how many texture
-+ * accesses are made and where so that we can do relocations for them in the
-+ * uniform stream.
-+ *
-+ * The kernel API has shaders stored in user-mapped BOs.  The BOs will be
-+ * forcibly unmapped from the process before validation, and any cache of
-+ * validated state will be flushed if the mapping is faulted back in.
-+ *
-+ * Storing the shaders in BOs means that the validation process will be slow
-+ * due to uncached reads, but since shaders are long-lived and shader BOs are
-+ * never actually modified, this shouldn't be a problem.

-Subject: [PATCH] drm/vc4: Drop struct_mutex around CL validation.
-
-We were using it so that we could make sure that shader validation
-state didn't change while we were validating, but now shader
-validation state is immutable.  The bcl/rcl generation doesn't do any
-other BO dereferencing, and seems to have no other global state
-dependency not covered by job_lock / bo_lock.
-
-Fixes a lock order reversal between mmap_sem and struct_mutex.

-Subject: [PATCH] Add support for the HiFiBerry DAC+ Pro.
-
-The HiFiBerry DAC+ and DAC+ Pro products both use the existing bcm sound driver with the DAC+ Pro having a special clock device driver representing the two high precision oscillators.
-
-An addition bug fix is included for the PCM512x codec where by the physical size of the sample frame is used in the calculation of the LRCK divisor as it was found to be wrong when using 24-bit depth sample contained in a little endian 4-byte sample frame.

-Subject: [PATCH] drm: Use the driver's gem_object_free function from CMA
- helpers.
-
-VC4 wraps the CMA objects in its own structures, so it needs to do its
-own teardown (waiting for GPU to finish, updating bo_stats tracking).
-The other CMA drivers are using drm_gem_cma_free_object as their
-gem_free_object, so this should be a no-op for them.

-Subject: [PATCH] drm/vc4: Add support for MSAA rendering.
-
-For MSAA, you set a bit in the binner that halves the size of tiles in
-each direction, so you can pack 4 samples per pixel in the tile
-buffer.  During rendering, you can load and store raw tile buffer
-contents (to save the per-sample MSAA contents), or you can load/store
-resolved tile buffer contents (loads spam the pixel value to all 4
-samples, and stores either average the 4 color samples, or store the
-first sample for Z/S).

-From: Eric Anholt <eric@anholt.net>
-Date: Tue, 8 Dec 2015 14:00:43 -0800
-Subject: [PATCH] drm/vc4: A few more non-functional changes to sync to
- upstream.
-
-At this point all that's left is the force-enable of HDMI connector,
-and using direct firmware calls to turn on V3D instead of the generic
-power domain support.

-Subject: [PATCH] Extend clock timeout, fix modprobe baudrate parameter.
-
-Set the BSC_CLKT clock streching timeout to 35ms as per SMBus specs.\n- Increase priority of baudrate parameter passed to modprobe (in /etc/modprobe.d/*.conf or command line). Currently custom baudrates don't work because they are overridden by clock-frequency in the platform_device passed to the function.

-Subject: [PATCH] BCM270X_DT: Add the sdtweak overlay, for tuning sdhost
-
-The sdhost overlay declares the sdhost interface and allows parameters
-to be set. This is overkill for situations where the user just wants to
-tweak the parameters of a pre-declared sdhost interface, so create an
-sdtweak overlay that does just that.

-
-This is required at least for SPDIF. If the bitrate goes above,
-videocore will either resample the audio or corrupt it due to
-underruns. Supposedly the hardware isn't designed to output
-higher rates, but it can still resample it down to supported
-rates.

-Some code is based on ac97_pcm.c.

-Report all layouts supported by the HDMI protocol to userspace.
-Make the videocore set the correct layout according to the
-userspace request.
-
-Some code taken from patch_hdmi.c. In particular, the HDMI channel
-layout table was copied without changes - with the idea in mind that
-hopefully it can be shared one day. Or at least updating it will be
-simpler.
-
-In my tests, everything appears to work, except when outputting
-FL FR RL RR. Then my receiver outputs RL on both the RL and RR
-speakers, while RR is never heard.

-Subject: [PATCH] bcm2835: access controls under the audio mutex
-
-I don't think the ALSA framework provides any kind of automatic
-synchronization within the control callbacks. We most likely need
-to ensure this manually, so add locking around all access to shared
-mutable data. In particular, bcm2835_audio_set_ctls() should
-probably always be called under our own audio lock.

-Subject: [PATCH] bcm2835: always use 2/4/8 channels for multichannel layouts
-
-Pad the unused channels with NA. This means userspace needs to write
-additional, silent padding channels, which is not ideal, but better
-than noise.
-
-Works around noise at the following channel counts: 3, 5, 6, 7

-Subject: [PATCH] bcm2835: only allow stereo if analogue jack is selected
-
-Sending more than 2 channels to videocore while outputting to analogue
-mysteriously outputs heavy artifacts. So just paint it over with a
-hack: if analogue is explicitly selected as destination, do not
-reporting support for anything other than stereo.
-
-I'm not sure how to deal with the auto case (destination 0). There's
-probably way to retrieve this and even to listen to plug events, but
-I didn't find one yet, and it's probably not worth the trouble. Just
-don't use this setting, I guess. Unless you like noise.
-
-Changing the setting while an audio stream is active also doesn't
-work properly. We could probably interrupt running streams by
-returning ENODEV or using kernel hotplug stuff (maybe), but that
-also doesn't seem worth the trouble.

-Subject: [PATCH] bcm2835: interpolate audio delay
-
-It appears the GPU only sends us a message all 10ms to update
-the playback progress. Other than this, the playback position
-(what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all.
-Userspace will see jitter up to 10ms in the audio position.
-
-Make this a bit nicer for userspace by interpolating the
-position using the CPU clock.
-
-I'm not sure if setting snd_pcm_runtime.delay is the right
-approach for this. Or if there is maybe an already existing
-mechanism for position interpolation in the ALSA core.
-
-I only set SNDRV_PCM_INFO_BATCH because this appears to remove
-at least one situation snd_pcm_runtime.delay is used, so I have
-to worry less in which place I have to update this field, or
-how it interacts with the rest of ALSA.
-
-In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY.
-One problem is that it requires sending a videocore message, and
-waiting for a reply, which could make the implementation much
-harder due to locking and synchronization requirements.

-Subject: [PATCH] bcm2835-sdhost: Add workaround for odd behaviour on some
- cards
-
-For reasons not understood, the sdhost driver fails when reading
-sectors very near the end of some SD cards. The problem could
-be related to the similar issue that reading the final sector
-of any card as part of a multiple read never completes, and the
-workaround is an extension of the mechanism introduced to solve
-that problem which ensures those sectors are always read singly.

-If the default MMC driver is bcm2835-sdhost:

-Subject: [PATCH] BCM270X_DT: Add sdio_overclock parameter to sdio overlay
-
-The sdio_overclock parameter is like the overclock_50 parameter, i.e.
-it sets an alternate frequency (in MHz) to use when the MMC framework
-requests 50MHz, except that it applies to the SDIO bus.
-
-Be aware that the actual frequencies achievable are limited to even integer
-divisions of 250MHz, and that the driver will round up to include fractions
-(e.g. 62 will include 62.5) but then round down to the nearest frequency.
-In other words, the chosen frequency is the highest possible that is less than
-the parameter value + 1. In practise this means that 62 is the only sensible
-value.
-
-Examples:
-  250MHz/4 = 62.5MHz (sdio_overclock=62)
-  250MHz/2 = 125MHz (sdio_overclock=125) # Too fast

-Subject: [PATCH] rtc: ds1307: add support for the DT property 'wakeup-source'
-
-For RTC chips with no IRQ directly connected to the SoC, the RTC chip
-can be forced as a wakeup source by stating that explicitly in
-the device's .dts file using the "wakeup-source" boolean property.
-This will guarantee the 'wakealarm' sysfs entry is available on the
-device, if supported by the RTC.
-
-With these changes to the driver rtc-ds1307 and the necessary entries
-in the .dts file, I get an working ds1337 RTC on the Witty Pi extension
-board by UUGear for the Raspberry Pi.
-
-An example for the entry in the .dts file:
-
-	rtc: ds1337@68 {
-		compatible = "dallas,ds1337";
-		reg = <0x68>;
-		wakeup-source;
-
-If the "wakeup-source" property is set, do not request an IRQ.
-Set also UIE mode to unsupported, to get a working 'hwclock' binary.

-Subject: [PATCH] FIXUP i2c_bcm2708: Don't change module baudrate parameter
-
-Overwriting the baudrate module parameter creates an apparent
-forced baudrate for i2c busses after the first. Not only does this
-override the baudrate from DT it also prevents the bus ID from
-being initialised.
-
-Also fix whitespace errors.

-Subject: [PATCH] bcm2835-sdhost: Major revision
-
-This is a significant revision of the bcm2835-sdhost driver. It
-improves on the original in a number of ways:
-
-1) Through the use of CMD23 for reads it appears to avoid problems
-   reading some sectors on certain high speed cards.
-2) Better atomicity to prevent crashes.
-3) Higher performance.
-4) Activity logging included, for easier diagnosis in the event
-   of a problem.

-Subject: [PATCH] Updated smsc95xx driver to check for a valid MAC address in
- eeprom before using smsc95xx.macaddr parameter passed on command line.
-
-The built-in RPi adaptor will still get a MAC address based on the parameter passed on the command line as the RPi hardware does not have an eeprom,
-however usb->ethernet adaptors using the same driver should have an eeprom with MAC address as part of their hardware and therefore will use this
-meaning they don't end up with the same MAC address as the built-in RPi adaptor.

-+This binding uses the common clock binding:
-+    Documentation/devicetree/bindings/clock/clock-bindings.txt
-+
-+The auxiliary peripherals (UART, SPI1, and SPI2) have a small register
-+area controlling clock gating to the peripherals, and providing an IRQ
-+status register.
-+
-+Required properties:
-+- compatible:	Should be "brcm,bcm2835-aux"
-+- #clock-cells:	Should be <1>. The permitted clock-specifier values can be
-+		  found in include/dt-bindings/clock/bcm2835-aux.h
-+- reg:		Specifies base physical address and size of the registers
-+- clocks:	The parent clock phandle
-+
-+Example:
-+
-+	clocks: cprman@7e101000 {
-+		compatible = "brcm,bcm2835-cprman";

-Subject: [PATCH] Aux SPI 1&2 implementation
-
-Adds aux spi 1 & 2 devices to compatible raspberry PIs.
-* Minor config of the driver build environment to ensure they get built
-for CONFIG_ARCH_BCM2708 & CONFIG_ARCH_BCM2709 devices.
-* Adds the aux spi driver into the defconfigs as a module.
-* Adds the auxiliary and spi1/2 devices into the device tree in a
-disabled state
-* Provides decide tree overlays which enables the devices and gives
-users a degree of control over how they are setup.

-Subject: [PATCH] ASoC: bcm: add missing .owner fields in sound card drivers
-
-If snd_soc_card.owner is not set the kernel won't do usage refcounting
-and one can remove the card driver module while it's in use (eg playback
-active) - which leads to a kernel crash.
-
-The missing owner field also prevents ALSA slot ordering
-(options snd slots=module-name1,module-name-2,...) from working with
-the I2S cards as it has no module name to match against.
-
-Fix these issues by setting the .owner field in the snd_soc_card structs.

-Subject: [PATCH] DT: Add overlays to configure I2C pins
-
-Lifted from
-https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=120938&p=825883
-so not claiming this to be my own work.
-Adds overlays i2c0-bcm2708 and i2c1-bcm2708 that allow the pin
-allocations for i2c-0 and i2c-1 to be changed.

-
-With both MMC controllers enabled there are few DMA channels left. The
-bcm2835-sdhost driver only uses DMA in one direction at a time, so it
-doesn't need to claim two channels.

-Subject: [PATCH] configfs: implement binary attributes
-
-ConfigFS lacked binary attributes up until now. This patch
-introduces support for binary attributes in a somewhat similar
-manner of sysfs binary attributes albeit with changes that
-fit the configfs usage model.
-
-Problems that configfs binary attributes fix are everything that
-requires a binary blob as part of the configuration of a resource,
-such as bitstream loading for FPGAs, DTBs for dynamically created
-devices etc.
-
-Look at Documentation/filesystems/configfs/configfs.txt for internals
-and howto use them.
-
-This patch is against linux-next as of today that contains
-Christoph's configfs rework.

-+There are two types of configfs attributes:

-+* Normal attributes, which similar to sysfs attributes, are small ASCII text

-+* Binary attributes, which are somewhat similar to sysfs binary attributes,
-+but with a few slight changes to semantics.  The PAGE_SIZE limitation does not
-+apply, but the whole binary item must fit in single kernel vmalloc'ed buffer.
-+The write(2) calls from user space are buffered, and the attributes'
-+write_bin_attribute method will be invoked on the final close, therefore it is
-+imperative for user-space to check the return code of close(2) in order to
-+verify that the operation finished successfully.
-+To avoid a malicious user OOMing the kernel, there's a per-binary attribute
-+maximum buffer value.

-Subject: [PATCH] OF: DT-Overlay configfs interface
-
-This is a port of Pantelis Antoniou's v3 port that makes use of the
-new upstreamed configfs support for binary attributes.
-
-Original commit message:
-
-Add a runtime interface to using configfs for generic device tree overlay
-usage. With it its possible to use device tree overlays without having
-to use a per-platform overlay manager.
-
-Please see Documentation/devicetree/configfs-overlays.txt for more info.
-
-Changes since v2:
-- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
-- Created a documentation entry
-- Slight rewording in Kconfig
-
-Changes since v1:
-- of_resolve() -> of_resolve_phandles().

-+Howto use the configfs overlay interface.
-+
-+A device-tree configfs entry is created in /config/device-tree/overlays
-+and and it is manipulated using standard file system I/O.
-+Note that this is a debug level interface, for use by developers and
-+not necessarily something accessed by normal users due to the
-+security implications of having direct access to the kernel's device tree.
-+
-+* To create an overlay you mkdir the directory:
-+
-+	# mkdir /config/device-tree/overlays/foo
-+
-+* Either you echo the overlay firmware file to the path property file.
-+
-+	# echo foo.dtbo >/config/device-tree/overlays/foo/path
-+
-+* Or you cat the contents of the overlay to the dtbo file
-+
-+	# cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
-+
-+The overlay file will be applied, and devices will be created/destroyed
-+as required.
-+
-+To remove it simply rmdir the directory.
-+
-+	# rmdir /config/device-tree/overlays/foo
-+
-+The rationalle of the dual interface (firmware & direct copy) is that each is
-+better suited to different use patterns. The firmware interface is what's
-+intended to be used by hardware managers in the kernel, while the copy interface
-+make sense for developers (since it avoids problems with namespaces).

-Subject: [PATCH] bcm2835-sdhost: Workaround for "slow" sectors
-
-Some cards have been seen to cause timeouts after certain sectors are
-read. This workaround enforces a minimum delay between the stop after
-reading one of those sectors and a subsequent data command.
-
-Using CMD23 (SET_BLOCK_COUNT) avoids this problem, so good cards will
-not be penalised by this workaround.

-Subject: [PATCH] drm/vc4: Fix the clear color for the first tile rendered.
-
-Apparently in hardware (as opposed to simulation), the clear colors
-need to be uploaded before the render config, otherwise they won't
-take effect.  Fixes igt's vc4_wait_bo/used-bo-* subtests.

-Subject: [PATCH] serial: Take care starting a hung-up tty's port
-
-tty_port_hangup sets a port's tty field to NULL (holding the port lock),
-but uart_tx_stopped, called from __uart_start (with the port lock),
-uses the tty field without checking for NULL.
-
-Change uart_tx_stopped to treat a NULL tty field as another stopped
-indication.

-Subject: [PATCH] bcm2835-sdhost: Adjust to core clock changes
-
-The SDHOST block uses the core clock, so previously it has been
-necessary to prevent the core clock from changing in order to maintain
-performance and prevent accidental SD bus overclocking.
-
-With this patch the sdhost driver is notified of clock changes, allowing
-it to delay them while an SD access is outstanding and to delay new SD
-accesses while the clock is changing. This feature is disabled in the
-case where the core frequency can never change.
-
-Now that the driver copes with changes to the core clock, it is safe
-to disable the io_is_busy feature of the on-demand governor.

-
-Add a skb_at_tc_ingress() as this will be needed elsewhere as well and
-can hide the ugly ifdef.

-Subject: [PATCH] bcm2835-sdhost: Precalc divisors and overclocks
-
-Recalculating the clock divisors when the core clock changes is wasteful
-and makes it harder to manage the overclock settings. Instead,
-precalculate them and only report significant changes.

-Subject: [PATCH] bcm2835-sdhost: Firmware manages the clock divisor
-
-The bcm2835-sdhost driver hands control of the CDIV clock divisor
-register to matching firmware, allowing it to adjust to a changing
-core clock. This removes the need to use the performance governor or
-to enable io_is_busy on the on-demand governor in order to get the
-best SD performance.
-
-N.B. As SD clocks must be an integer divisor of the core clock, it is
-possible that the SD clock for "turbo" mode can be different (even
-lower) than "normal" mode.
-

-Subject: [PATCH] BCM270X_DT: Don't generate "linux,phandle" props
-
-The EPAPR standard says to use "phandle" properties to store phandles,
-rather than the deprecated "linux,phandle" version. By default, dtc
-generates both, but adding "-H epapr" causes it to only generate
-"phandle"s, saving some space and clutter.

-Subject: [PATCH] V4L2 driver updates (#1393)
-
-* BCM2835-V4L2: Correct ISO control and add V4L2_CID_ISO_SENSITIVITY_AUTO
-
-https://github.com/raspberrypi/linux/issues/1251
-
-V4L2_CID_ISO_SENSITIVITY was not advertising ISO*1000 as it should.
-V4L2_CID_ISO_SENSITIVITY_AUTO was not implemented, so was taking
-V4L2_CID_ISO_SENSITIVITY as 0 for auto mode.
-Still accepts 0 for auto, but also abides by the new parameter.
-
-Signed-off-by: Dave Stevenson <6by9@users.noreply.github.com>
-
-* BCM2835-V4L2: Add a video_nr parameter.
-
-Adds a kernel parameter "video_nr" to specify the preferred
-/dev/videoX device node.
-https://www.raspberrypi.org/forums/viewtopic.php?f=38&t=136120&p=905545
-
-Signed-off-by: Dave Stevenson <6by9@users.noreply.github.com>
-
-* BCM2835-V4L2: Add support for multiple cameras
-
-Ask GPU on load how many cameras have been detected, and
-enumerate that number of devices.
-Only applicable on the Compute Module as no other device
-exposes multiple CSI2 interfaces.
-
-Signed-off-by: Dave Stevenson <6by9@users.noreply.github.com>
-
-* BCM2835-V4L2: Add control of the overlay location and alpha.
-
-Actually do something useful in vidioc_s_fmt_vid_overlay and
-vidioc_try_fmt_vid_overlay, rather than effectively having
-read-only fields.
-
-Signed-off-by: Dave Stevenson <6by9@users.noreply.github.com>
-
-* BCM2835-V4L2: V4L2-Compliance failure fix
-
-VIDIOC_TRY_FMT was failing due to bytesperline not
-being set correctly by default.
-
-Signed-off-by: Dave Stevenson <6by9@users.noreply.github.com>
-
-* BCM2835-V4L2: Make all module parameters static
-
-Clean up to correct variable scope
-

-Subject: [PATCH] bcm2835-sdhost: Reset the clock in task context

-Since reprogramming the clock can now involve a round-trip to the
-firmware it must not be done at atomic context, and a tasklet
-is not a task.

-Subject: [PATCH] bcm2835: add fallback channel layouts if channel map API is
- not used
-
-Should be more useful than just forcing stereo.
-
-We can't match the exact legacy ALSA channel layouts, so this is a
-"best effort" hack.
-
-I'm not sure what happens if the application requests channel counts
-that are not power-of-2s. The channel map API hopefully forces
-applications which use the channel map API to request the correct
-count by adding padding channels, but the bare API enforces
-nothing. Possibly this could be added to rate_hw_constraint_channels
-at a later point.

-Subject: [PATCH] clk: bcm2835: Support for clock parent selection
-
-Some bcm2835 clocks used by hardware (like "PWM" or "H264") can have multiple
-parent clocks. These clocks divide the rate of a parent which can be selected by
-setting the proper bits in the clock control register.
-
-Previously all these parents where handled by a mux clock. But a mux clock
-cannot be used because updating clock control register to select parent needs a
-password to be xor'd with the parent index.
-
-This patch get rid of mux clock and make these clocks handle their own parent,
-allowing them to select the one to use.

-Subject: [PATCH] clk: bcm2835: correctly enable fractional clock support
-
-The current driver calculates the clock divider with
-fractional support enabled.
-
-But it does not enable fractional support in the
-control register itself resulting in an integer only divider,
-but in clk_set_rate responds back the fractionally divided
-clock frequency.
-
-This patch enables fractional support in the control register
-whenever there is a fractional bit set in the requested clock divider.
-
-Mash clock limits are are also handled for the PWM clock
-applying the correct divider limits (2 and max_int) applicable to
-basic fractional divider support (mash order of 1).
-
-It also adds locking to protect the read/modify/write cycle of
-the register modification.
-
-Fixes: 41691b8862e2 ("clk: bcm2835: Add support for programming the
-audio domain clocks")

-Subject: [PATCH] clk: bcm2835: expose raw clock-registers via debugfs
-
-For debugging purposes under some circumstance
-it helps to be able to see the actual clock registers.
-
-E.g: when looking at the clock divider it is helpful to
-see what the actual clock divider is.
-
-This patch exposes all the clock registers specific to each
-clock/pll/pll-divider via debugfs.

-Subject: [PATCH] clk: bcm2835: remove use of BCM2835_CLOCK_COUNT in driver
-
-As the use of BCM2835_CLOCK_COUNT in
-include/dt-bindings/clock/bcm2835.h is frowned upon as
-it needs to get modified every time a new clock gets introduced
-this patch changes the clk-bcm2835 driver to use a different
-scheme for registration of clocks and pll, so that there
-is no more need for BCM2835_CLOCK_COUNT to be defined.

-Subject: [PATCH] clk: bcm2835: reorganize bcm2835_clock_array assignment
-
-Reorganize bcm2835_clock_array so that there is no more
-need for separate bcm2835_*_data structures to be defined.
-Instead the required structures are generated inline via
-helper macros.
-
-To allow this to also work for pll alone it was required that
-the parent_pll was changed from a pointer to bcm2835_pll_data
-to the name of the pll instead.
-

-Subject: [PATCH] ARM: bcm2835: add rpi power domain driver
-
-This patch adds support for several power domains on Raspberry Pi,
-including USB (so it can be enabled even if the bootloader didn't do
-it), and graphics.
-
-This patch is the combined work of Eric Anholt (who wrote USB support
-inside of the Raspberry Pi firmware driver, and wrote the non-USB
-domain support) and Alexander Aring (who separated the original USB
-work out from the firmware driver).

-Subject: [PATCH] ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency
-
-The firmware driver can be a loadable module, but the power domain
-can only be built-in, so we get a build error in an allmodconfig
-kernel:
-
-:(.text+0x17e59c): undefined reference to `rpi_firmware_property'
-:(.text+0x17e51c): undefined reference to `rpi_firmware_get'
-:(.text+0x17e244): undefined reference to `rpi_firmware_property'
-
-This changes the dependency to only allow the power domain code
-to be enabled when the firmware driver is built-in. Other users
-of the firmware driver may still be loadable modules and not
-everyone needs the power domains, so we don't change the firmware
-code.

-Subject: [PATCH] drm/vc4: copy_to_user() returns the number of bytes remaining
-
-The copy_to/from_user() functions return the number of bytes remaining
-to be copied.  We want to return error codes here.
-
-Also it's a bad idea to print an error message if a copy from user fails
-because users can use that to spam /var/log/messages which is annoying
-so I removed those.

-Fixes: 214613656b51 ('drm/vc4: Add an interface for capturing the GPU state after a hang.')

-Subject: [PATCH] drm/vc4: Add a proper short-circut path for legacy cursor
- updates.
-
-Previously, on every modeset we would allocate new display list
-memory, recompute changed planes, write all of them to the new memory,
-and pointed scanout at the new list (which will latch approximately at
-the next line of scanout).  We let
-drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait
-for a vblank after a modeset before cleaning up the old state and
-letting the next modeset proceed, and on legacy cursor updates we
-wouldn't wait.  If you moved the cursor fast enough, we could
-potentially wrap around the display list memory area and overwrite the
-existing display list while it was still being scanned out, resulting
-in the HVS scanning out garbage or just halting.
-
-Instead of making cursor updates wait for scanout to move to the new
-display list area (which introduces significant cursor lag in X), we
-just rewrite our current display list.
-

-So far, we've only ever lit up one CRTC, so this has been fine.  To

-run our display lists into each other.

-From: Eric Anholt <eric@anholt.net>
-Date: Tue, 20 Oct 2015 16:06:57 +0100
-Subject: [PATCH] drm/vc4: Add support for scaling of display planes.
-
-This implements a simple policy for choosing scaling modes
-(trapezoidal for decimation, PPF for magnification), and a single PPF
-filter (Mitchell/Netravali's recommendation).
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-(cherry picked from commit 21af94cf1a4c2d3450ab7fead58e6e2291ab92a9)

-From: Eric Anholt <eric@anholt.net>
-Date: Wed, 30 Dec 2015 12:25:44 -0800
-Subject: [PATCH] drm/vc4: Add support for YUV planes.
-
-This supports 420 and 422 subsampling with 2 or 3 planes, tested with
-modetest.  It doesn't set up chroma subsampling position (which it
-appears KMS doesn't deal with yet).
-
-The LBM memory is overallocated in many cases, but apparently the docs
-aren't quite correct and I'll probably need to look at the hardware
-source to really figure it out.
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-(cherry picked from commit fc04023fafecf19ebd09278d8d67dc5ed1f68b46)

-Subject: [PATCH] drm/vc4: Fix spurious GPU resets due to BO reuse.
-
-We were tracking the "where are the head pointers pointing" globally,
-so if another job reused the same BOs and execution was at the same
-point as last time we checked, we'd stop and trigger a reset even
-though the GPU had made progress.

-Subject: [PATCH] drm/vc4: improve throughput by pipelining binning and
- rendering jobs
-
-The hardware provides us with separate threads for binning and
-rendering, and the existing model waits for them both to complete
-before submitting the next job.
-
-Splitting the binning and rendering submissions reduces idle time and
-gives us approx 20-30% speedup with some x11perf tests such as -line10
-and -tilerect1.  Improves openarena performance by 1.01897% +/-
-0.247857% (n=16).
-
-Thanks to anholt for suggesting this.
-
-v2: Rebase on the spurious resets fix (change by anholt).

-
-The original Raspberry Pi had the GPIO active high, but the later
-models are active low.  The DT GPIO bindings allow specifying the
-active flag, except that it doesn't get propagated to the gpiodesc, so
-you have to handle it yourself.

-We occasionally found a duplicate message from 16

-
-While only one thread adds completions, without the

-Subject: [PATCH] BCM270X_DT: Sound DT adjustments for Dynamic DT
-
-There are a number of issues when loading and unloading overlays for
-sound cards:
-1) The "sound" and "audio" nodes must be children of a bus node, such
-   as "/soc", otherwise the DT changes don't result in platform devices
-   being created and deleted.
-2) The "/sound" node must have a "disabled" status property, otherwise
-   setting the status to "okay" won't be detected.
-3) ALSA doesn't like having components unloaded under its feet, and it
-   is easy to deadlock or crash. Ordering the overlay fragments so that
-   the sound card appears last avoids this problem.

-Subject: [PATCH] Allow up to 24dB digital gain to be applied when using
- IQAudIO DAC
-
-24db_digital_gain DT param can be used to specify that PCM512x
-codec "Digital" volume control should not be limited to 0dB gain,
-and if specified will allow the full 24dB gain.

-Subject: [PATCH] BCM270X_DT: Move vc4 node contents to bcm2708_common.dtsi.
-
-This should clarify what's going on with the overlay: The hardware is
-always present, we're just enabling the DT node so that the vc4 driver
-probes.
-
-The interrupts are left in the overlay, because the firmware doesn't
-check node status before masking out the vc4 interrupts.
-
-By having the nodes in the common file, we'll be able to correctly
-connect the HDMI HPD GPIO so that we can detect whether an HDMI
-monitor is connected.

-Subject: [PATCH] drm: Add an encoder and connector type enum for DPI.
-
-Right now exynos is exposing DPI as a TMDS encoder and VGA connector,
-which seems rather misleading.  This isn't just an internal detail,
-since xrandr actually exposes "VGA" as the output name.  Define some
-new enums so that vc4's DPI can have a more informative name.
-
-I considered other names for the connector as well.  For VC4, the
-Adafruit DPI kippah takes the 28 GPIO pins and routes them to a
-standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely
-identify an ordering of pins (apparently some other orderings exist),
-doesn't explain things as well for the user (who, if anything, knows
-their product is a DPI kippah/panel combo), and actually doesn't have
-to exist (one could connect the 28 GPIOs directly to something else).
-Simply "DPI" seems like a good compromise name to distinguish from the
-HDMI, DSI, and TV connectors .

-Subject: [PATCH] drm/vc4: Add support for gamma ramps.
-
-We could possibly save a bit of power by not requesting gamma
-conversion when the ramp happens to be 1:1, but at least if all the
-CRTCs are off the SRAM will be disabled.
-
-This should fix brightness sliders in a lot of fullscreen games.

- 4.4+
-
-get_vblank_counter hooked up to drm_vblank_count() which alway was
-non-sensical but didn't hurt in the past. Since Linux 4.4 it
-triggers a WARN_ON_ONCE in drm_update_vblank_count on first vblank
-irq disable, so fix it by hooking to drm_vblank_no_hw_counter().
-
-Tested against Raspian kernel 4.4.8 tree on RPi 2B.

-
-The async page flip path was missing drm_crtc_vblank_get/put
-completely. The sync flip path was missing a vblank put, so async
-flips only reported proper pageflip completion events by chance,
-and vblank irq's never turned off after a first vsync'ed page flip
-until system reboot.

-
-Now that overlay parameters are applied before the merge (a requirement
-for kernel runtime overlays) it is illegal for parameters/overrides to
-target nodes in the base DTB. Solve the problem of only enabling I2C
-when an RTC option is used by making the RTC fragments conditional,
-and including the required status="okay" within the fragments.

-
-These divide off of PLLD_PER and are used for the ethernet and wifi
-PHYs source PLLs.  Neither of them is currently represented by a phy
-device that would grab the clock for us.
-
-This keeps other drivers from killing the networking PHYs when they
-disable their own clocks and trigger PLLD_PER's refcount going to 0.
-
-v2: Skip marking as critical if they aren't on at boot.

-Subject: [PATCH] clk: bcm2835: Skip PLLC clocks when deciding on a new clock
- parent
-
-If the firmware had set up a clock to source from PLLC, go along with
-it.  But if we're looking for a new parent, we don't want to switch it
-to PLLC because the firmware will force PLLC (and thus the AXI bus
-clock) to different frequencies during over-temp/under-voltage,
-without notification to Linux.
-
-On my system, this moves the Linux-enabled HDMI state machine and DSI1
-escape clock over to plld_per from pllc_per.  EMMC still ends up on
-pllc_per, because the firmware had set it up to use that.
-

-Subject: [PATCH] mmc: Add card_quirks module parameter, log quirks
-
-Use mmc_block.card_quirks to override the quirks for all SD or MMC
-cards. The value is a bitfield using the bit positions defined in
-include/linux/mmc/card.h. If the module parameter is placed in the
-kernel command line (or bootargs) stored on the card then, assuming the
-device only has one SD card interface, the override effectively becomes
-card-specific.

-Subject: [PATCH] rtc: ds1307: ensure that any pending alarm is cleared before
- a new alarm is enabled
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If a previously-set alarm was disabled and then triggered, it may still
-be pending when a new alarm is configured.
-
-Then, if the alarm is enabled before the pending alarm is cleared, then
-an interrupt is immediately raised.
-
-Unfortunately, when the alarm is cleared and enabled during the same I²C
-block write, the chip (at least the DS1339 I have) considers that the
-alarm is enabled before it is cleared, and raises an interrupt.
-
-This patch ensures that the pending alarm is cleared before the alarm is
-enabled.

-
-This reverts commit 7da44d06540b4a191ecc74e943f3203577fce0df.
-
-This breaks the driver on Pi3 as hotplug is implemented through a
-gpio expander owned by the GPU.
-
-We need to extend the virtual gpio driver to support this, but for
-now assume hotplug is always enabled.

-Subject: [PATCH] simple: add sound-dai-cells to I2S def
-
-Add '#sound-dai-cells = <0>;' to the I2S definition in
-bcm2708_common.dtsi
-
-Not having it specified, whilst not causing an issue right now with
-rpi-4.4.y, is going to cause an issue going forward with the use of
-simple-card driver. So it doesn't fall through the cracks, patch it
-in now.
-
-Hopefully Martin has taken care of getting a patch submitted for the
-upstream Pi dts, as it was he who first run into the issue with the
-current upstream kernel....

-Subject: [PATCH] BCM2835-V4L2: Correct handling for BGR24 vs RGB24.
-
-There was a bug in the GPU firmware that had reversed these
-two formats.
-Detect the old firmware, and reverse the formats if necessary.

-Subject: [PATCH] [media] rc: gpio-ir-recv: add timeout on idle
-
-Many decoders require a trailing space (period without IR illumination)
-to be delivered before completing a decode.
-
-Since the gpio-ir-recv driver only delivers events on gpio transitions,
-a single IR symbol (caused by a quick touch on an IR remote) will not
-be properly decoded without the use of a timer to flush the tail end
-state of the IR receiver.
-
-This patch initializes and uses a timer and the timeout field of rcdev
-to complete the stream and allow decode.
-
-The timeout can be overridden through the use of the LIRC_SET_REC_TIMEOUT
-ioctl.

-Subject: [PATCH] BCM270X_DT: Fix rpi-dac overlay
-
-The rpi-dac overlay is almost identical to the hifiberry-dac overlay -
-the codec used is different but it also doesn't sit on the I2C bus. As
-a result, when the overlays were modified for dynamic loading and it
-was discovered that the hifiberry-dac overlay didn't work any more, the
-the rpi-dac overlay was also broken.
-
-The failure was caused by the fact that outside a bus, device names are
-constructed from the concatenation of the path elements leading to it,
-so moving the codec instantiation inside /soc caused the device name
-to get a "soc" added, breaking ALSA's naming.

-Subject: [PATCH] dmaengine: bcm2835: remove unnecessary masking of dma
- channels
-
-The original patch contained 3 dma channels that were masked out.
-
-These - as far as research and discussions show - are a
-artefacts remaining from the downstream legacy dma-api.
-
-Right now down-stream still includes a legacy api used only
-in a single (downstream only) driver (bcm2708_fb) that requires
-2D DMA for speedup (DMA-channel 0).
-Formerly the sd-card support driver also was using this legacy
-api (DMA-channel 2), but since has been moved over to use
-dmaengine directly.
-
-The DMA-channel 3 is already masked out in the devicetree in
-the default property "brcm,dma-channel-mask = <0x7f35>;"
-
-So we can remove the whole masking of DMA channels.

-Subject: [PATCH] dmaengine: bcm2835: limit max length based on channel type
-
-The bcm2835 dma system has 2 basic types of dma-channels:
-* "normal" channels
-* "light" channels
-
-Lite channels are limited in several aspects:
-* internal data-structure is 128 bit (not 256)
-* does not support BCM2835_DMA_TDMODE (2D)
-* DMA length register is limited to 16 bit.
-  so 0-65535 (not 0-65536 as mentioned in the official datasheet)
-* BCM2835_DMA_S/D_IGNORE are not supported
-
-The detection of the type of mode is implemented by looking at
-the LITE bit in the DEBUG register for each channel.
-This allows automatic detection.
-
-Based on this the maximum block size is set to (64K - 4) or to 1G
-and this limit is honored during generation of control block
-chains. The effect is that when a LITE channel is used more
-control blocks are used to do the same transfer (compared
-to a normal channel).
-
-As there are several sources/target DREQS that are 32 bit wide
-we need to have the transfer to be a multiple of 4 as this would
-break the transfer otherwise.
-
-This is why the limit of (64K - 4) was chosen over the
-alternative of (64K - 4K).

-Subject: [PATCH] dmaengine: bcm2835: add slave_sg support to bcm2835-dma
-
-Add slave_sg support to bcm2835-dma using shared allocation
-code for bcm2835_desc and DMA-control blocks already used by
-dma_cyclic.
-
-Note that bcm2835_dma_callback had to get modified to support
-both modes of operation (cyclic and non-cyclic).
-
-Tested using:
-* Hifiberry I2S card (using cyclic DMA)
-* fb_st7735r SPI-framebuffer (using slave_sg DMA via spi-bcm2835)
-playing BigBuckBunny for audio and video.

-Subject: [PATCH] dmaengine: bcm2835: use platform_get_irq_byname
-
-Use platform_get_irq_byname to allow for correct mapping of
-interrupts to dma channels.
-
-The currently implemented device tree is unfortunately
-implemented with the wrong assumption, that each dma-channel
-has its own dma channel, but dma-irq 11 is handling
-dma-channel 11-14 and dma-irq 12 is actually a "catch all"
-interrupt.
-
-So here we use the byname variant and require that interrupts
-are explicitly named via the interrupts-name property in the
-device tree.
-
-The use of shared interrupts is also implemented.
-
-As a side-effect this means we can now use dma channels 12, 13 and 14
-in a correct manner - also testing shows that onl using
-channels 11 to 14 for spi and i2s works perfectly (when playing
-some video)

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Load driver early since at least bcm2708_fb doesn't support deferred
-probing and even if it did, we don't want the video driver deferred.
-
-Support the legacy DMA API which is needed by bcm2708_fb
-(but only using the dedicated dma channel 0).

-Subject: [PATCH] dmaengine: bcm2835: Fix cyclic DMA period splitting
-
-The code responsible for splitting periods into chunks that
-can be handled by the DMA controller missed to update total_len,
-the number of bytes processed in the current period, when there
-are more chunks to follow.
-
-Therefore total_len was stuck at 0 and the code didn't work at all.
-This resulted in a wrong control block layout and audio issues because
-the cyclic DMA callback wasn't executing on period boundaries.
-
-Fix this by adding the missing total_len update.

-Subject: [PATCH] dmaengine: bcm2835: Avoid splitting periods into very small
- chunks
-
-The current cyclic DMA period splitting implementation can generate
-very small chunks at the end of each period. For example a 65536 byte
-period will be split into a 65532 byte chunk and a 4 byte chunk on
-the "lite" DMA channels.
-
-This increases pressure on the RAM controller as the DMA controller
-needs to fetch two control blocks from RAM in quick succession and
-could potentially cause latency issues if the RAM is tied up by other
-devices.
-
-We can easily avoid these situations by distributing the remaining
-length evenly between the last-but-one and the last chunk, making
-sure that split chunks will be at least half the maximum length the
-DMA controller can handle.
-
-This patch checks if the last chunk would be less than half of
-the maximum DMA length and if yes distributes the max len+4...max_len*1.5
-bytes evenly between the last 2 chunks. This results in chunk sizes
-between max_len/2 and max_len*0.75 bytes.

-
-The tx_status hook is supposed to be safe to call from interrupt
-context, but it wouldn't ever return completion for the last transfer,
-meaning you couldn't poll for DMA completion with interrupts masked.
-
-This fixes IRQ handling for bcm2835's DSI1, which requires using the
-DMA engine to write its registers due to a bug in the AXI bridge.

-Subject: [PATCH] Added support for headphones, microphone and bclk_ratio
- settings.
-
-This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added.

-Subject: [PATCH] IQaudIO: auto-mute for AMP+ and DigiAMP+
-
-IQAudIO amplifier mute via GPIO22. Add dt params for "one-shot" unmute
-and auto mute.
-
-Revision 2, auto mute implementing HiassofT suggestion to mute/unmute
-using set_bias_level, rather than startup/shutdown....
-"By default DAPM waits 5 seconds (pmdown_time) before shutting down
-playback streams so a close/stop immediately followed by open/start
-doesn't trigger an amp mute+unmute."
-
-Tested on both AMP+ (via DAC+) and DigiAMP+, with both options...
-
-dtoverlay=iqaudio-dacplus,unmute_amp
- "one-shot" unmute when kernel module loads.
-
-dtoverlay=iqaudio-dacplus,auto_mute_amp
- Unmute amp when ALSA device opened by a client. Mute, with 5 second delay
- when ALSA device closed. (Re-opening the device within the 5 second close
- window, will cancel mute.)
-
-Revision 4, using gpiod.
-
-Revision 5, clean-up formatting before adding mute code.
- - Convert tab plus 4 space formatting to 2x tab
- - Remove '// NOT USED' commented code
-
-Revision 6, don't attempt to "one-shot" unmute amp, unless card is
-successfully registered.

-Subject: [PATCH] Add critical information for getting pi3-miniuart-bt overlay
- to work
-
-Bluetooth on RPi 3 using uart1 will not work without setting core_freq=250 in config.txt. This is not
-documented anywhere, so this seems like a good place to start.

-Subject: [PATCH] bcm2835-sdhost: Improvements to error recovery
-
-1) Try to avoid reducing overclock when a card is removed.
-
-2) Reset overclock on card insertion.
-
-3) Reduce logging when errors occur, lowering the severity of
-   some messages and making others conditional on the debug
-   flag.
-
-4) Attempt to identify a disconnected SD bus earlier, treating a
-   zero returned OCR (voltage support) as an error condition.

-commit cf5ef3a299ba32f6ac24c3c6ba18c1b7f1b5475f upstream.
-
-This patch adds 32 bit word capability to the wm8731 driver. The wm8731
-codec is capable of handling 32 bit word sizes, however that has not
-previously been activated in the codec driver.

-Subject: [PATCH] vchiq_arm: Avoid use of mutex in add_completion
-
-Claiming the completion_mutex within add_completion did prevent some
-messages appearing twice, but provokes a deadlock caused by vcsm using
-vchiq within a page fault handler.
-
-Revert the use of completion_mutex, and instead fix the original
-problem using more memory barriers.

-Subject: [PATCH] fix auto-sense in lirc_rpi driver
-
-On a Raspberry Pi 2, the lirc_rpi driver might receive spurious
-interrupts and change it's low-active / high-active setting.
-When this happens, the IR remote control stops working.
-
-This patch disables this auto-detection if the 'sense' parameter
-was set in the device tree, making the driver robust to such
-spurious interrupts.

-Subject: [PATCH] clk: bcm2835: Mark the CM SDRAM clock's parent as critical
-
-While the SDRAM is being driven by its dedicated PLL most of the time,
-there is a little loop running in the firmware that periodically turns
-on the CM SDRAM clock (using its pre-initialized parent) and switches
-SDRAM to using the CM clock to do PVT recalibration.
-
-This avoids system hangs if we choose SDRAM's parent for some other
-clock, then disable that clock.

-Subject: [PATCH] clk: bcm2835: Don't rate change PLLs on behalf of dividers.
-
-Our core PLLs are intended to be configured once and left alone.  With
-the flag set, asking to set the PLLD_DSI1 clock rate would change PLLD
-just to get closer to the requested DSI clock, thus changing PLLD_PER,
-the UART and ethernet PHY clock rates downstream of it, and breaking
-ethernet.

-Subject: [PATCH] drm/fb_cma_helper: Remove implicit call to
- disable_unused_functions
-
-The drm_fbdev_cma_init function always calls the
-drm_helper_disable_unused_functions. Since it's part of the usual probe
-process, all the drivers using that helper will end up having their encoder
-and CRTC disable functions called at probe if their device has not been
-reported as enabled.
-
-This could be fixed by reading out from the registers the current state of
-the device if it is enabled, but even that will not handle the case where
-the device is actually disabled.
-
-Moreover, the drivers using the atomic modesetting expect that their enable
-and disable callback to be called when the device is already enabled or
-disabled (respectively).
-
-We can however fix this issue by moving the call to
-drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the
-drivers needing it (all the drivers calling drm_fbdev_cma_init and not
-using the atomic modesetting) explicitly call it.

-Subject: [PATCH] drm/mipi-dsi: Allow to build drm-mipi-dsi as a module
-
-The drm-mipi-dsi driver has been only built-in although this isn't
-strictly required to be so.  Since it's referred by lots of DRM
-drivers nowadays, most of distro kernels include the driver as
-built-in as a result, even though many systems don't need it at all.
-
-This patch fixes Kconfig to allow drm-mipi-dsi driver built as a
-module, so that we can save footprint on systems without such DRM
-drivers.  The probe order is managed by the module dependency, and
-postcore_initcall() works just fine as a module init call.

-From fe5b388ac8cacd61ca01ff9a89f60af401fffee9 Mon Sep 17 00:00:00 2001
-From: Eric Anholt <eric@anholt.net>
-Date: Wed, 10 Feb 2016 11:42:32 -0800
-Subject: [PATCH] drm/vc4: Add DSI1 driver
-
-The DSI0 and DSI1 blocks on the 2835 are different but very similar
-hardware blocks.  Some registers move around, and the featureset is
-slightly different, but they're clearly related.  This doesn't enable
-DSI0, but some of the infrastructure is present.
-
-Also, this driver doesn't initialize the DSI successfully from
-poweron, so we currently require that the Raspberry Pi firmware enable
-it at boot time.  From there, we just keep the same settings forever,
-and when poweroff is requested we just scan out black instead.
-

-+ * The 7" touchscreen consists of a DPI LCD panel, a Toshiba

-+ * controlling power management, the LCD PWM, and the touchscreen.

-Subject: [PATCH] drm/vc4: Make pageflip completion handling more robust.
-
-Protect both the setup of the pageflip event and the
-latching of the new requested displaylist head pointer
-by the event lock, so we can't get into a situation
-where vc4_atomic_flush latches the new display list via
-HVS_WRITE, then immediately gets preempted before queueing
-the pageflip event, then the page-flip completes in hw and
-the vc4_crtc_handle_page_flip() runs and no-ops due to
-lack of a pending pageflip event, then vc4_atomic_flush
-continues and only then queues the pageflip event - after
-the page flip handling already no-oped. This would cause
-flip completion handling only at the next vblank - one
-frame too late.
-
-In vc4_crtc_handle_page_flip() check the actual DL head
-pointer in SCALER_DISPLACTX against the requested pointer
-for page flip to make sure that the flip actually really
-completed in the current vblank and doesn't get deferred
-to the next one because the DL head pointer was written
-a bit too late into SCALER_DISPLISTX, after start of
-vblank, and missed the boat. This avoids handling a
-pageflip completion too early - one frame too early.
-
-According to Eric, DL head pointer updates which were
-written into the HVS DISPLISTX reg get committed to hardware
-at the last pixel of active scanout. Our vblank interrupt
-handler, as triggered by PV_INT_VFP_START irq, gets to run
-earliest at the first pixel of HBLANK at the end of the
-last scanline of active scanout, ie. vblank irq handling
-runs at least 1 pixel duration after a potential pageflip
-completion happened in hardware.
-
-This ordering of events in the hardware, together with the
-lock protection and SCALER_DISPLACTX sampling of this patch,
-guarantees that pageflip completion handling only runs at
-exactly the vblank irq of actual pageflip completion in all
-cases.
-
-Background info from Eric about the relative timing of
-HVS, PV's and trigger points for interrupts, DL updates:
-
-https://lists.freedesktop.org/archives/dri-devel/2016-May/107510.html
-
-Tested on RPi 2B with hardware timing measurement equipment
-and shown to no longer complete flips too early or too late.

- allocation
-
-There is redundant code in the clean up exit path when dpi_connector
-fails to be allocated.  The current code checks if connector is NULL
-before destroying it, in fact, connector is NULL at this point so
-the check is redundant and can be removed. The final clean up is
-that we can remove the goto fail with a simple return and the unused
-variable ret.

-Subject: [PATCH] drm/vc4: Implement precise vblank timestamping.
-
-Precise vblank timestamping is implemented via the
-usual scanout position based method. On VC4 the
-pixelvalves PV do not have a scanout position
-register. Only the hardware video scaler HVS has a
-similar register which describes which scanline for
-the output is currently composited and stored in the
-HVS fifo for later consumption by the PV.
-
-This causes a problem in that the HVS runs at a much
-faster clock (system clock / audio gate) than the PV
-which runs at video mode dot clock, so the unless the
-fifo between HVS and PV is full, the HVS will progress
-faster in its observable read line position than video
-scan rate, so the HVS position reading can't be directly
-translated into a scanout position for timestamp correction.
-
-Additionally when the PV is in vblank, it doesn't consume
-from the fifo, so the fifo gets full very quickly and then
-the HVS stops compositing until the PV enters active scanout
-and starts consuming scanlines from the fifo again, making
-new space for the HVS to composite.
-
-Therefore a simple translation of HVS read position into
-elapsed time since (or to) start of active scanout does
-not work, but for the most interesting cases we can still
-get useful and sufficiently accurate results:
-
-1. The PV enters active scanout of a new frame with the
-   fifo of the HVS completely full, and the HVS can refill
-   any fifo line which gets consumed and thereby freed up by
-   the PV during active scanout very quickly. Therefore the
-   PV and HVS work effectively in lock-step during active
-   scanout with the fifo never having more than 1 scanline
-   freed up by the PV before it gets refilled. The PV's
-   real scanout position is therefore trailing the HVS
-   compositing position as scanoutpos = hvspos - fifosize
-   and we can get the true scanoutpos as HVS readpos minus
-   fifo size, so precise timestamping works while in active
-   scanout, except for the last few scanlines of the frame,
-   when the HVS reaches end of frame, stops compositing and
-   the PV catches up and drains the fifo. This special case
-   would only introduce minor errors though.
-
-2. If we are in vblank, then we can only guess something
-   reasonable. If called from vblank irq, we assume the irq is
-   usually dispatched with minimum delay, so we can take a
-   timestamp taken at entry into the vblank irq handler as a
-   baseline and then add a full vblank duration until the
-   guessed start of active scanout. As irq dispatch is usually
-   pretty low latency this works with relatively low jitter and
-   good results.
-
-   If we aren't called from vblank then we could be anywhere
-   within the vblank interval, so we return a neutral result,
-   simply the current system timestamp, and hope for the best.
-
-Measurement shows the generated timestamps to be rather precise,
-and at least never off more than 1 vblank duration worst-case.
-
-Limitations: Doesn't work well yet for interlaced video modes,
-             therefore disabled in interlaced mode for now.
-
-v2: Use the DISPBASE registers to determine the FIFO size (changes
-    by anholt)

-Subject: [PATCH] drm/vc4: Enable runtime PM.
-
-This may actually get us a feature that the closed driver didn't have:
-turning off the GPU in between rendering jobs, while the V3D device is
-still opened by the client.
-
-There may be some tuning to be applied here to use autosuspend so that
-we don't bounce the device's power so much, but in steady-state
-GPU-bound rendering we keep the power on (since we keep multiple jobs
-outstanding) and even if we power cycle on every job we can still
-manage at least 680 fps.
-
-More importantly, though, runtime PM will allow us to power off the
-device to do a GPU reset.
-
-v2: Switch #ifdef to CONFIG_PM not CONFIG_PM_SLEEP (caught by kbuild
-    test robot)
-

-Subject: [PATCH] drm/vc4: Replace HDMI force-connected with an EDID probe.
-
-The force-connected started out because I didn't know how to read the
-HPD pin successfully, which required the hpd_active_low check and
-getting the correct active level into the DTs.  It stayed because we
-don't have the Pi3's HPD line exposed to Linux, so this was the only
-way to bring up graphics on it.
-
-However, with the DSI panel support now present, users want to be able
-to run DSI-only systems, and forcing HDMI on is interfering with
-default screen configurations.  Work around the Pi3's missing HPD by
-probing the DDC on I2C and see if it's present at all.

-+* Microchip ENC28J60
-+
-+This is a standalone 10 MBit ethernet controller with SPI interface.
-+
-+For each device connected to a SPI bus, define a child node within
-+the SPI master node.
-+
-+Required properties:
-+- compatible: Should be "microchip,enc28j60"
-+- reg: Specify the SPI chip select the ENC28J60 is wired to
-+- interrupt-parent: Specify the phandle of the source interrupt, see interrupt
-+                    binding documentation for details. Usually this is the GPIO bank
-+                    the interrupt line is wired to.
-+- interrupts: Specify the interrupt index within the interrupt controller (referred
-+              to above in interrupt-parent) and interrupt type. The ENC28J60 natively
-+              generates falling edge interrupts, however, additional board logic
-+              might invert the signal.
-+- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
-+- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
-+             see also generic and your platform specific pinctrl binding
-+             documentation.
-+
-+Optional properties:
-+- spi-max-frequency: Maximum frequency of the SPI bus when accessing the ENC28J60.
-+  According to the ENC28J80 datasheet, the chip allows a maximum of 20 MHz, however,
-+  board designs may need to limit this value.
-+- local-mac-address: See ethernet.txt in the same directory.
-+
-+
-+Example (for NXP i.MX28 with pin control stuff for GPIO irq):
-+
-+        ssp2: ssp@80014000 {
-+                compatible = "fsl,imx28-spi";
-+                pinctrl-names = "default";
-+                pinctrl-0 = <&spi2_pins_b &spi2_sck_cfg>;
-+                status = "okay";
-+
-+                enc28j60: ethernet@0 {
-+                        compatible = "microchip,enc28j60";
-+                        pinctrl-names = "default";
-+                        pinctrl-0 = <&enc28j60_pins>;
-+                        reg = <0>;
-+                        interrupt-parent = <&gpio3>;
-+                        interrupts = <3 IRQ_TYPE_EDGE_FALLING>;
-+                        spi-max-frequency = <12000000>;
-+                };
-+        };
-+
-+        pinctrl@80018000 {
-+                enc28j60_pins: enc28j60_pins@0 {
-+                        reg = <0>;

-Subject: [PATCH] enc28j60: Fix race condition in enc28j60 driver
-
-(Upstream commit 373819ec391de0d11f63b10b2fb69ef2854236ca)
-
-The interrupt worker code for the enc28j60 relies only on the TXIF flag to
-determinate if the packet transmission was completed. However the datasheet
-specifies in section 12.1.3 that TXERIF will clear the TXRTS after a
-transmit abort. Also in section 12.1.4 that TXIF will be set
-when TXRTS transitions from '1' to '0'. Therefore the TXIF flag is enabled
-during transmission errors.
-
-This causes a race condition, since the worker code will invoke
-enc28j60_tx_clear() -> netif_wake_queue(), potentially invoking the
-ndo_start_xmit function to send a new packet. The enc28j60_send_packet function
-uses a workqueue that invokes enc28j60_hw_tx(). In between this function is
-called, the worker from the interrupt handler will enter the path for error
-handler because of the TXERIF flag, causing to invoke enc28j60_tx_clear() again
-and releasing the packet scheduled for transmission, causing a kernel crash with
-due a NULL pointer.
-
-These crashes due a NULL pointer were observed under stress conditions of the
-device. A BUG_ON() sequence was used to validate the issue was fixed, and has
-been running without problems for 2 years now.

-Subject: [PATCH] drm/vc4: Add a getparam ioctl for getting the V3D identity
- regs.
-
-As I extend the driver to support different V3D revisions, userspace
-needs to know what version it's targeting.  This is most easily
-detected using the V3D identity registers.
-
-v2: Make sure V3D is runtime PM on when reading the registers.
-v3: Switch to a 64-bit param value (suggested by Rob Clark in review)
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> (v2)
-Reviewed-by: Rob Clark <robdclark@gmail.com> (v3, over irc)
-(cherry picked from commit af713795c59fea36161a7debf97dbc10bf652cf7)
-
-v4: Squashed in "drm/vc4: Fix handling of a pm_runtime_get_sync() success case."

-Subject: [PATCH] drm/vc4: Add a bitmap of branch targets during shader
- validation.
-
-This isn't used yet, it's just a first step toward loop validation.
-During the main parsing of instructions, we need to know when we hit a
-new basic block so that we can reset validated state.
-
-v2: Fix a stray semicolon after an if block.  (caught by kbuild test).

-Subject: [PATCH] drm/vc4: Add support for branching in shader validation.
-
-We're already checking that branch instructions are between the start
-of the shader and the proper PROG_END sequence.  The other thing we
-need to make branching safe is to verify that the shader doesn't read
-past the end of the uniforms stream.
-
-To do that, we require that at any basic block reading uniforms have
-the following instructions:
-
-load_imm temp, <next offset within uniform stream>
-add unif_addr, temp, unif
-
-The instructions are generated by userspace, and the kernel verifies
-that the load_imm is of the expected offset, and that the add adds it
-to a uniform.  We track which uniform in the stream that is, and at
-draw call time fix up the uniform stream to have the address of the
-start of the shader's uniforms at that location.
-

-Subject: [PATCH] drm/vc4: Fix overflow mem unreferencing when the binner runs
- dry.
-
-Overflow memory handling is tricky: While it's still referenced by the
-BPO registers, we want to keep it from being freed.  When we are
-putting a new set of overflow memory in the registers, we need to
-assign the old one to the last rendering job using it.
-
-We were looking at "what's currently running in the binner", but since
-the bin/render submission split, we may end up with the binner
-completing and having no new job while the renderer is still
-processing.  So, if we don't find a bin job at all, look at the
-highest-seqno (last) render job to attach our overflow to.

-
-Make sure FIFO gets cleared before trying to send
-data in case of a repeated start (COMBINED=Y).
-
-* i2c: fix i2c_bcm2708: Only write to FIFO when not full
-
-Check if FIFO can accept data before writing.
-To avoid a peripheral read on the last iteration of a loop,
-both bcm2708_bsc_fifo_fill and ~drain are changed as well.

-Subject: [PATCH] bcm2835-sdhost: Don't exit cmd wait loop on error
-
-The FAIL flag can be set in the CMD register before command processing
-is complete, leading to spurious "failed to complete" errors. This has
-the effect of promoting harmless CRC7 errors during CMD1 processing
-into errors that can delay and even prevent booting.
-
-Also:
-1) Convert the last KERN_ERROR message in the register dumping to
-   KERN_INFO.
-2) Remove an unnecessary reset call from  bcm2835_sdhost_add_host.

-Subject: [PATCH] drm/vc4: Allow some more signals to be packed with uniform
- resets.
-
-The intent was to make sure people don't sneak in a small immediate or
-something to change the interpretation of the uniform update args, but
-these signals are just fine.
-
-Fixes a validation failure in the current X server on some Render
-operation.

-Subject: [PATCH] BCM270X: Add an overlay for enabling the vc4 driver in
- firmware-KMS mode.
-
-This gets us normal 3D support on top of the existing firmware display
-stack.  There's no real modesetting support, no async pageflips
-(hurting performance), etc., but it means that the desktop can at
-least run until we get full native modesetting.

-Subject: [PATCH] Allo Piano DAC boards: Initial 2 channel (stereo) support
- (#1645)
-
-Add initial 2 channel (stereo) support for Allo Piano DAC (2.0/2.1) boards,
-using allo-piano-dac-pcm512x-audio overlay and allo-piano-dac ALSA ASoC
-machine driver.
-
-NB. The initial support is 2 channel (stereo) ONLY!
-(The Piano DAC 2.1 will only support 2 channel (stereo) left/right output,
- pending an update to the upstream pcm512x codec driver, which will have
- to be submitted via upstream. With the initial downstream support,
- provided by this patch, the Piano DAC 2.1 subwoofer outputs will
- not function.)

-Subject: [PATCH] drm/vc4: Fix races when the CS reads from render targets.
-
-With the introduction of bin/render pipelining, the previous job may
-not be completed when we start binning the next one.  If the previous
-job wrote our VBO, IB, or CS textures, then the binning stage might
-get stale or uninitialized results.
-
-Fixes the major rendering failure in glmark2 -b terrain.

-Signed-off-by: Eric Anholt <eric@anholt.net>
-Fixes: ca26d28bbaa3 ("drm/vc4: improve throughput by pipelining binning and rendering jobs")

-Subject: [PATCH] drm/vc4: Fix handling of interlaced video modes.
-
-We must not apply CRTC_INTERLACE_HALVE_V to interlaced modes during
-mode enumeration, as drm_helper_probe_single_connector_modes
-does, so wrap it and reset the effect of CRTC_INTERLACE_HALVE_V
-on affected interlaced modes.
-
-Also mode_fixup interlaced modes passed in from user space.
-
-This fixes the vblank timestamping constants and entries in
-the mode->crtc_xxx fields needed for precise vblank timestamping.

-
-On top of the interlaced video mode fix and with some additional

-Subject: [PATCH] drm/vc4: Fix support for interlaced modes on HDMI.
-
-We really do need to be using the halved V fields.  I had been
-confused by the code I was using as a reference because it stored
-halved vsync fields but not halved vdisplay, so it looked like I only
-needed to divide vdisplay by 2.
-
-This reverts part of Mario's timestamping fixes that prevented
-CRTC_HALVE_V from applying, and instead adjusts the timestamping code
-to not use the crtc field in that case.
-
-Fixes locking of 1920x1080x60i on my Dell 2408WFP.  There are black
-bars on the top and bottom, but I suspect that might be an
-under/overscan flags problem as opposed to video timings.

-Subject: [PATCH] drm/vc4: Add support for double-clocked modes.
-
-Now that we have infoframes to report the pixel repeat flag, we can
-start using it.  Fixes locking the 720x480i and 720x576i modes on my
-Dell 2408WFP.  Like the 1920x1080i case, they don't fit properly on
-the screen, though.

-Subject: [PATCH] x86/boot: Fix kdump, cleanup aborted E820_PRAM max_pfn
- manipulation
-
-commit 917db484dc6a69969d317b3e57add4208a8d9d42 upstream.
-
-In commit:
-
-  ec776ef6bbe1 ("x86/mm: Add support for the non-standard protected e820 type")
-
-Christoph references the original patch I wrote implementing pmem support.
-The intent of the 'max_pfn' changes in that commit were to enable persistent
-memory ranges to be covered by the struct page memmap by default.
-
-However, that approach was abandoned when Christoph ported the patches [1], and
-that functionality has since been replaced by devm_memremap_pages().
-
-In the meantime, this max_pfn manipulation is confusing kdump [2] that
-assumes that everything covered by the max_pfn is "System RAM".  This
-results in kdump hanging or crashing.

- [2]: https://bugzilla.redhat.com/show_bug.cgi?id=1351098
-
-So fix it.

-Subject: [PATCH] drm/vc4: Fix termination of the initial scan for branch
- targets.
-
-The loop is scanning until the original max_ip (size of the BO), but
-we want to not examine any code after the PROG_END's delay slots.
-There was a block trying to do that, except that we had some early
-continue statements if the signal wasn't a PROG_END or a BRANCH.
-
-The failure mode would be that a valid shader is rejected because some
-undefined memory after the PROG_END slots is parsed as a branch and
-the rest of its setup is illegal.  I haven't seen this in the wild,
-but valgrind was complaining when about this up in the userland
-simulator mode.

-
-The validation for it ends up being quite simple, but I hadn't got
-around to it before merging the driver.  For backwards compatibility,
-we also need to add a flag so that the userspace GL driver can easily
-tell if the kernel will allow ETC1 textures (on an old kernel, it will
-continue to convert to RGBA8)

-Subject: [PATCH] drm/vc4: Use runtime autosuspend to avoid thrashing V3D power
- state.
-
-The pm_runtime_put() we were using immediately released power on the
-device, which meant that we were generally turning the device off and
-on once per frame.  In many profiles I've looked at, that added up to
-about 1% of CPU time, but this could get worse in the case of frequent
-rendering and readback (as may happen in X rendering).  By keeping the
-device on until we've been idle for a couple of frames, we drop the
-overhead of runtime PM down to sub-.1%.

-Subject: [PATCH] drm/vc4: Use drm_gem_object_unreference_unlocked
-
-Since my last struct_mutex crusade someone escaped!
-
-This already has the advantage that for the common case when someone
-else holds a ref the unref won't even acquire dev->struct_mutex. And
-I'm working on code to allow drivers to completely opt-out of any and
-all dev->struct_mutex usage, but that only works if they use the
-_unlocked variants everywhere.
-
-v2: Drop comment too.
-
-v3: Drop the other comment too.

-
-FS threading brings performance improvements of 0-20% in glmark2.
-
-The validation code checks for thread switch signals and ensures that
-the registers of the other thread are not touched, and that our clamps
-are not live across thread switches.  It also checks that the
-threading and branching instructions do not interfere.
-
-(Original patch by Jonas, changes by anholt for style cleanup,
-removing validation the kernel doesn't need to do, and adding the flag
-for userspace).
-
-v2: Minor style fixes from checkpatch.

-Subject: [PATCH] [Audioinjector] Fix bit offsets for equal volume and add 8
- kHz operation (#1727)
-
-Applying to the audioinjector sound card only. This patch offsets channel
-2 correctly from the LR clock. This ensures that channel 2 doesn't loose
-any bits during capture. It also results in both channels 1 and 2 having
-the same volume. This commit also adds 8 kHz operation.

-Subject: [PATCH] kbuild: add -fno-PIE
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 8ae94224c9d72fc4d9aaac93b2d7833cf46d7141 upstream.
-
-Debian started to build the gcc with -fPIE by default so the kernel
-build ends before it starts properly with:
-|kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
-
-Also add to KBUILD_AFLAGS due to:
-
-|gcc -Wp,-MD,arch/x86/entry/vdso/vdso32/.note.o.d … -mfentry -DCC_USING_FENTRY … vdso/vdso32/note.S
-|arch/x86/entry/vdso/vdso32/note.S:1:0: sorry, unimplemented: -mfentry isn’t supported for 32-bit in combination with -fpic
-
-Tagging it stable so it is possible to compile recent stable kernels as
-well.

-Subject: [PATCH] kbuild: Steal gcc's pie from the very beginning
-
-commit c6a385539175ebc603da53aafb7753d39089f32e upstream.
-
-So Sebastian turned off the PIE for kernel builds but that was too late
-- Kbuild.include already uses KBUILD_CFLAGS and trying to disable gcc
-options with, say cc-disable-warning, fails:
-
-  gcc -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs
-  ...
-  -Wno-sign-compare -fno-asynchronous-unwind-tables -Wframe-address -c -x c /dev/null -o .31392.tmp
-  /dev/null:1:0: error: code model kernel does not support PIC mode
-
-because that returns an error and we can't disable the warning. For
-example in this case:
-
-KBUILD_CFLAGS   += $(call cc-disable-warning,frame-address,)
-
-which leads to gcc issuing all those warnings again.
-
-So let's turn off PIE/PIC at the earliest possible moment, when we
-declare KBUILD_CFLAGS so that cc-disable-warning picks it up too.
-
-Also, we need the $(call cc-option ...) because -fno-PIE is supported
-since gcc v3.4 and our lowest supported gcc version is 3.2 right now.

-Subject: [PATCH] BCM270X_DT: Update UART0 clock-frequency
-
-The Raspberry Pi firmware now sets the UART0 clock frequency to
-48MHz (was 3MHz), to allow for baudrates up to 3MHz. This value
-is overwritten by the firmware, but alternative loaders such
-as U-Boot ignore the firmware-provided DTB. And besides, the
-default ought to be correct.

-Subject: [PATCH] Revert "HID: dragonrise: fix HID Descriptor for 0x0006 PID"
-
-[ Upstream commit 1bcaa05ebee115213e34f1806cc6a4f7a6175a88 ]
-This reverts commit 18339f59c3a6 ("HID: dragonrise: fix HID...") because it
-breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage
-caused by commit 79346d620e9d ("HID: input: force generic axis to be mapped
-to their user space axis"), it is probable that the manufacturer released
-different hardware with the same PID so this fix works for only a subset
-and breaks the other gamepads sharing the PID.
-
-What is needed is another more generic solution which fixes 79346d620e9d
-("HID: input: force generic axis ...") breakage for this controller: we
-need to add an exception for this driver to make it keep the old behaviour
-previous to the initial breakage (this is done in patch 2 of this series).

-Subject: [PATCH] configfs: Remove ppos increment in configfs_write_bin_file
-
-[ Back-port of f8608985f851c917b3884b692d8e326b0210d34e ]
-
-The simple_write_to_buffer() already increments the @ppos on success,
-see fs/libfs.c simple_write_to_buffer() comment:
-
-"
-On success, the number of bytes written is returned and the offset @ppos
-advanced by this number, or negative value is returned on error.
-"
-
-If the configfs_write_bin_file() is invoked with @count smaller than the
-total length of the written binary file, it will be invoked multiple times.
-Since configfs_write_bin_file() increments @ppos on success, after calling
-simple_write_to_buffer(), the @ppos is incremented twice.
-
-Subsequent invocation of configfs_write_bin_file() will result in the next
-piece of data being written to the offset twice as long as the length of
-the previous write, thus creating buffer with "holes" in it.
-
-The simple testcase using DTO follows:
-  $ mkdir /sys/kernel/config/device-tree/overlays/1
-  $ dd bs=1 if=foo.dtbo of=/sys/kernel/config/device-tree/overlays/1/dtbo
-Without this patch, the testcase will result in twice as big buffer in the
-kernel, which is then passed to the cfs_overlay_item_dtbo_write() .

-
-Bring bcm2709_defconfig up to the level of bcmrpi_defconfig with
-respect to USB support. This is prompted by the introduction of CM3,
-which makes gadget mode on 2709/2710 a useful option.

-Subject: [PATCH] drm/vc4: Fix sending of page flip completion events in FKMS
- mode.
-
-In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
-CRTC's atomic flush handler that moved the completion event from the
-proposed atomic state change to the CRTC's current state.  That meant
-that when full screen pageflipping happened (glxgears -fullscreen in
-X, compton, por weston), the app would end up blocked firever waiting
-to draw its next frame.

-Subject: [PATCH] clk: bcm: Support rate change propagation on bcm2835 clocks
-
-Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set
-to a precise rate (in our case 108MHz). With the current implementation,
-where peripheral clocks are not allowed to forward rate change requests
-to their parents, it is impossible to match this requirement unless the
-bootloader has configured things correctly, or a specific rate has been
-assigned through the DT (with the assigned-clk-rates property).
-
-Add a new field to struct bcm2835_clock_data to specify which parent
-clocks accept rate change propagation, and support set rate propagation
-in bcm2835_clock_determine_rate().

-Subject: [PATCH] clk: bcm2835: Don't rate change PLLs on behalf of DSI PLL
- dividers (v2).
-
-Our core PLLs are intended to be configured once and left alone.  With
-the SET_RATE_PARENT, asking to set the PLLD_DSI1 clock rate would
-change PLLD just to get closer to the requested DSI clock, thus
-changing PLLD_PER, the UART and ethernet PHY clock rates downstream of
-it, and breaking ethernet.
-
-We *do* want PLLH to change so that PLLH_AUX can be exactly the value
-we want, though.  Thus, we need to have a per-divider policy of
-whether to pass rate changes up.
