-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.
-

-
-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'.

-dwc_otg: fix summarize urb->actual_length for isochronous transfers
-
-Kernel does not copy input data of ISO transfers to userspace
-if actual_length is set only in ISO transfers and not summarized
-in urb->actual_length. Fixes raspberrypi/linux#903
-
-fiq_fsm: Use correct states when starting isoc OUT transfers
-
-In fiq_fsm_start_next_periodic() if an isochronous OUT transfer
-was selected, no regard was given as to whether this was a single-packet
-transfer or a multi-packet staged transfer.
-
-For single-packet transfers, this had the effect of repeatedly sending
-OUT packets with bogus data and lengths.
-
-Eventually if the channel was repeatedly enabled enough times, this
-would lock up the OTG core and no further bus transfers would happen.
-
-Set the FSM state up properly if we select a single-packet transfer.
-
-Fixes https://github.com/raspberrypi/linux/issues/1842
-
-dwc_otg: make nak_holdoff work as intended with empty queues
-
-If URBs reading from non-periodic split endpoints were dequeued and
-the last transfer from the endpoint was a NAK handshake, the resulting
-qh->nak_frame value was stale which would result in unnecessarily long
-polling intervals for the first subsequent transfer with a fresh URB.
-
-Fixup qh->nak_frame in dwc_otg_hcd_urb_dequeue and also guard against
-a case where a single URB is submitted to the endpoint, a NAK was
-received on the transfer immediately prior to receiving data and the
-device subsequently resubmits another URB past the qh->nak_frame interval.
-
-Fixes https://github.com/raspberrypi/linux/issues/1709
-
-dwc_otg: fix split transaction data toggle handling around dequeues
-
-See https://github.com/raspberrypi/linux/issues/1709
-
-Fix several issues regarding endpoint state when URBs are dequeued
-- If the HCD is disconnected, flush FIQ-enabled channels properly
-- Save the data toggle state for bulk endpoints if the last transfer
- from an endpoint where URBs were dequeued returned a data packet
-- Reset hc->start_pkt_count properly in assign_and_init_hc()
-
-dwc_otg: fix several potential crash sources
-
-On root port disconnect events, the host driver state is cleared and
-in-progress host channels are forcibly stopped. This doesn't play
-well with the FIQ running in the background, so:
-- Guard the disconnect callback with both the host spinlock and FIQ
- spinlock
-- Move qtd dereference in dwc_otg_handle_hc_fsm() after the early-out
- so we don't dereference a qtd that has gone away
-- Turn catch-all BUG()s in dwc_otg_handle_hc_fsm() into warnings.
-
-dwc_otg: delete hcd->channel_lock
-
-The lock serves no purpose as it is only held while the HCD spinlock
-is already being held.
-
-dwc_otg: remove unnecessary dma-mode channel halts on disconnect interrupt
-
-Host channels are already halted in kill_urbs_in_qh_list() with the
-subsequent interrupt processing behaving as if the URB was dequeued
-via HCD callback.
-
-There's no need to clobber the host channel registers a second time
-as this exposes races between the driver and host channel resulting
-in hcd->free_hc_list becoming corrupted.

-dwc_otg: make periodic scheduling behave properly for FS buses
-
-If the root port is in full-speed mode, transfer times at 12mbit/s
-would be calculated but matched against high-speed quotas.
-
-Reinitialise hcd->frame_usecs[i] on each port enable event so that
-full-speed bandwidth can be tracked sensibly.
-
-Also, don't bother using the FIQ for transfers when in full-speed

-
-Constrain queuing non-periodic split transactions so they are performed

-
-Even if the error is solved by including the missing
-DWC_TASK_HI_SCHEDULE function, the kernel will panic when loading
-dwc_otg.
-
-As a workaround, simply prevent user from building dwc_otg as a module
-as the current kernel does not support it.

-dwc_otg: Fix a regression when dequeueing isochronous transfers
-
-In 282bed95 (dwc_otg: make nak_holdoff work as intended with empty queues)
-the dequeue mechanism was changed to leave FIQ-enabled transfers to run
-to completion - to avoid leaving hub TT buffers with stale packets lying
-around.
-
-This broke FIQ-accelerated isochronous transfers, as this then meant that
-dozens of transfers were performed after the dequeue function returned.
-
-Restore the state machine fence for isochronous transfers.

-dwc_otg: add smp_mb() to prevent driver state corruption on boot
-
-Occasional crashes have been seen where the FIQ code dereferences
-invalid/random pointers immediately after being set up, leading to
-panic on boot.
-
-The crash occurs as the FIQ code races against hcd_init_fiq() and
-the hcd_init_fiq() code races against the outstanding memory stores
-from dwc_otg_hcd_init(). Use explicit barriers after touching
-driver state.

-usb: dwc_otg: fix memory corruption in dwc_otg driver
-
-[Upstream commit 51b1b6491752ac066ee8d32cc66042fcc955fef6]
-
-The move from the staging tree to the main tree exposed a
-longstanding memory corruption bug in the dwc2 driver. The
-reordering of the driver initialization caused the dwc2 driver
-to corrupt the initialization data of the sdhci driver on the
-Raspberry Pi platform, which made the bug show up.
-
-The error is in calling to_usb_device(hsotg->dev), since ->dev
-is not a member of struct usb_device. The easiest fix is to
-just remove the offending code, since it is not really needed.
-
-Thanks to Stephen Warren for tracking down the cause of this.

-+ * 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 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

-+ *
-+ * 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

-+ *
-+ * 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.

-+ * 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
