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'. - -Signed-off-by: Noralf Trønnes

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...

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. -+ */ -+ -+ -+/* #define VERBOSE_DEBUG */ -+/* #define DUMP_MSGS */ -+ -+ -+#include <linux/blkdev.h> -+#include <linux/completion.h> -+#include <linux/dcache.h> -+#include <linux/delay.h> -+#include <linux/device.h> -+#include <linux/fcntl.h> -+#include <linux/file.h> -+#include <linux/fs.h> -+#include <linux/kref.h> -+#include <linux/kthread.h> -+#include <linux/limits.h> -+#include <linux/module.h> -+#include <linux/rwsem.h> -+#include <linux/slab.h> -+#include <linux/spinlock.h> -+#include <linux/string.h> -+#include <linux/freezer.h> -+#include <linux/utsname.h> -+ -+#include <linux/usb/ch9.h> -+#include <linux/usb/gadget.h> -+ -+#include "gadget_chips.h" -+ -+ -+ -+/* -+ * Kbuild is not very cooperative with respect to linking separately -+ * compiled library objects into one module.

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. -+ * -+ */ -+ -+#ifdef __cplusplus -+} -+#endif -+ -+#endif /* _DWC_OS_H_ */ ---- /dev/null -+++ b/drivers/usb/host/dwc_common_port/usb.h -@@ -0,0 +1,946 @@ -+/* -+ * Copyright (c) 1998 The NetBSD Foundation, Inc. -+ * All rights reserved. -+ * -+ * This code is derived from software contributed to The NetBSD Foundation -+ * by Lennart Augustsson (lennart@augustsson.net) at -+ * Carlstedt Research & Technology. -+ * -+ * Redistribution and use in source and binary forms, with or without -+ * modification, are permitted provided that the following conditions -+ * are met: -+ * 1.
