2007-03-26USB: omap_udc: workaround dma_free_coherent() bogosityDavid Brownell
Various fixes to omap_udc, noted with some recent testing: - Cope with some SMP-induced braindamage in ARM's dma_{alloc,free}_coherent() implementation: alloc() can be called with IRQs blocked, but since late last year that's no longer true for free(). This resolves really NASTY problems with logspamming via WARN_ON(), indicating N-page leaks. - Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the previous code only handled RECIP_INTERFACE, this version should be correct except for (sigh) bulk/interrupt endpoints. - Provide a better name for the function reporting whether the board has vbus sensing wired up. GET_STATUS requests for endpoint status still acts strangely though, at least given one flakey host doesn't always ack the first DATA packet, then the packet that gets retransmitted doesn't have data!

2007-03-10Revert "USB: pxa2xx_udc: fix hardcoded irq number"Linus Torvalds
This reverts commit d2487cb4257dafb686f682285854fe7f02ca29d8. Russell King points out that it's obviously bogus, and I have to agree. Not only does "irq" not even exist in that scope, but we obviously need to free the irq that we actually requested, and that's IRQ_USB.

2007-02-16USB: at91_udc, shrink runtime footprintDavid Brownell
This is a runtime codespace shrink: in most cases, platform devices should put probe() should in the init section, and remove() in the exit section. And I have no idea why the module init/exit routines were mismarked. It also moves one function table into read-only data.

2007-02-16USB: fix g_serial small errorBryan O'Donoghue
A SET_LINE_CODING control request should return a zero length packet as an ACK to the host, during the status phase of a USB transaction. The return value of gs_setup_class() is treated as the number of bytes to write in the status phase of the control request, by gs_setup(). For this case, the value returned by gs_setup_class should be zero for SET_LINE_CODING but, right now, appears to be sizeof(struct usb_cdc_line_coding). However, if after doing the memcpy of the line coding descriptor we set the variable "ret" to be zero, we should return the appropiate ZLP to the host as an ACK in the status phase of the control request. I've tested this out using Linux as both host and slave and confirmed that the following small change fixes the spurious return of sizeof(struct usb_cdc_line_coding)/wLength bytes in the status phase of a USB_CDC_REQ_SET_LINE_CODING request. It's not a huge bug but, it is worth fixing. Signed-off-by: Bryan O'Donoghue <bodonoghue@codehermit.ie> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-08[ARM] 4141/1: consolidate functions that handles gpio in pxa2xx_udcMilan Svoboda
This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get. These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions. Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq). This is next step to make pxa2xx_udc fully work on ixp4xx platform. Signed-off-by: Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-02-07USB: gadgetfs AIO tweaksAlan Stern
This patch (as837) fixes several mistakes in the AIO interface of the gadgetfs driver: The ki_retry method is not supposed to do a put on the kiocb. The extra call to aio_put_req() causes memory corruption. (Note: This call was removed before, by patch as691, and then mysteriously re-introduced later.) Even if a read transfer is cancelled, we can and should send to the user all the data that did manage to get transferred. Testing for AIO cancellation in the I/O completion handler is both racy and (now) unnecessary. aio_complete() does its own checking, in a safe manner.

2007-02-07USB: gadgetfs race fixDavid Brownell
This resolves a race in gadgetfs associated with changing device/ep0 when processing control requests.

2007-02-07USB: ethernet gadget interop with MCCI Windows driverDavid Brownell
It turns out that minor tweaks to the "CDC Subset" support in the Ethernet gadget driver, just updating a config descriptor, let it be automagically recognized by a Windows driver supported by MCCI. This patch adds those descriptors, so systems using PXA 255 processors (like Gumstix etc) can interop with those commercial MS-Windows drivers. This is a Good Thing since Microsoft's RNDIS code has bugginess issues, which are unfortunately compounded by "won't fix" issues as well as "the published specs are incomplete and wrong" issues. Being able to talk to the MCCI driver gives Windows users another connectivity option. (MCCI also has CDC Ethernet drivers, which can help most non-PXA processors.)

2006-12-07[PATCH] Add include/linux/freezer.h and move definitions from sched.hNigel Cunningham
Move process freezing functions from include/linux/sched.h to freezer.h, so that modifications to the freezer or the kernel configuration don't require recompiling just about everything.

2006-12-01USB: net2280: don't send unwanted zero-length packetsAlan Stern
The net2280 driver is too eager to send zero-length packets when IN tokens are received on ep0. No such packet should be sent (the driver should NAK) before the gadget driver has queued the proper response. Otherwise deferred responses are impossible. This patch (as823) makes net2280 avoid sending ZLPs for IN transfers on ep0 until a response has been submitted, and avoids stalling when an OUT packet is received before a request has been submitted for an OUT transfer on ep0.

2006-12-01[ARM] 3963/1: AT91: Update configuration filesAndrew Victor
A number of configuration file changes. These are mainly to replace references to ARCH_AT91RM9200 and ARCH_AT91SAM9261 with the common/generic ARCH_AT91. That way we don't need to mention every specific AT91 processor explicitly. Also adds the configuration option for AT91SAM9260-EK and AT91SAM9261-EK boards.
