2009-02-27USB: musb: fix data toggle saving with shared FIFOSergei Shtylyov
For some strange reason the host side musb_giveback() decides that it's always got an IN transfer when the hardware endpoint is using a shared FIFO. This causes musb_save_toggle() to read the toggle state from the RXCSR register instead of TXCSR, and may also cause unneeded reloading of RX endpoint registers.

2009-02-27USB: musb: host endpoint_disable() oops fixesSergei Shtylyov
The musb_h_disable() routine can oops in some cases: - It's not safe to read hep->hcpriv outside musb->lock, since it gets changed on completion IRQ paths. - The list iterators aren't safe to use in that way; just remove the first element while !list_empty(), so deletions on other code paths can't make trouble. We need two "scrub the list" loops because only one branch should touch hardware and advance the schedule.

2009-02-27USB: musb: fix urb_dequeue() methodSergei Shtylyov
The urb_dequeue() method forgets to unlink 'struct musb_qh' from the control or bulk schedules when the URB being cancelled is the only one queued to its endpoint. That will cause musb_advance_schedule() to block once it reaches 'struct musb_qh' with now empty URB list, so URBs queued for other endpoints after the one being dequeued will not be served. Fix by unlinking the QH from the list except when it's already being handled (typically by musb_giveback). Since a QH with an empty URB list is now supposed to be freed, do that. And remove a now-useless check from musb_advance_schedule().

The input queue should be used for TX on endpoints which share FIFO hardware. The host TX path wasn't doing that.

2009-02-27usb: musb: make Davinci *work* in mainlineDavid Brownell
Now that the musb build fixes for DaVinci got merged (RC3?), kick in the other bits needed to get it finally *working* in mainline: - Use clk_enable()/clk_disable() ... the "always enable USB clocks" code this originally relied on has since been removed. - Initialize the USB device only after the relevant I2C GPIOs are available, so the host side can properly enable VBUS. - Tweak init sequencing to cope with mainline's relatively late init of the I2C system bus for power switches, transceivers, and so on. Sanity tested on DM6664 EVM for host and peripheral modes; that system won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also verified on OMAP3.

2009-02-27USB: usb_get_string should check the descriptor typeAlan Stern
This patch (as1218) fixes a problem with a radio-control joystick used in the "walkera 4#3" helicopter. This device responds to the initial Get-String-Descriptor request for string 0 (which is really the list of supported languages) by sending its config descriptor! The usb_get_string() routine needs to check whether it got the right type of descriptor. Oddly enough, this sort of check is already present in usb_get_descriptor(). The patch changes the error code from -EPROTO to -ENODATA, because -EPROTO shows up in so many other contexts to indicate a hardware failure rather than a firmware error.

2009-02-27USB: EHCI: slow down ITD reuseKarsten Wiese
Currently ITDs are immediately recycled whenever their URB completes. However, EHCI hardware can sometimes remember some ITD state. This means that when the ITD is reused before end-of-frame it may sometimes cause the hardware to reference bogus state. This patch defers reusing such ITDs by moving them into a new ehci member cached_itd_list. ITDs resting in cached_itd_list are moved back into their stream's free_list once scan_periodic() detects that the active frame has elapsed. This makes the snd_usb_us122l driver (in kernel since .28) work right when it's hooked up through EHCI.

2009-02-26V4L/DVB (10694): [PATCH] software IRQ watchdog for Flexcop B2C2 DVB PCI cardsPatrick Boettcher
With (some) Technisat cards you cannot run multiple DVB applications in parallel and switch the channel at the same time. There seems to be a problem on the interfaces or even inside the flexcop-device that can't handle interruption on the streaming interface. This patch adds a watchdog to check whether data is supposed to come in (streaming PIDs are requested) and if no data is seen within 400ms (default) it resets the streaming/pid-filtering hardware. This patch is urgently needed to support the rev 2.8 of the hardware and solves problem occassionally seen on older hardware.

2009-02-25sata_mv: fix SoC interrupt breakageMark Lord
For some reason, sata_mv doesn't clear interrupt status during init when it's running on an SoC host adapter. If the bootloader has touched the SATA controller before starting Linux, Linux can end up enabling the SATA interrupt with events pending, which will cause the interrupt to be marked as spurious and then be disabled, which then breaks all further accesses to the controller. This patch makes the SoC path clear interrupt status on init like in the non-SoC case.

2009-02-25pata_it821x: resume from hibernation fails with RAID volumeOndrej Zary
Hibernation didn't work for me since I started to use IT8212 controller. I did some debugging (booting with no_console_suspend init=/bin/sh). Found that resume fails (2.6.28) with "serial number mismatch 'some garbage' != 'some other garbage'" and "revalidation failed" messages. That's because the controller firmware fills different serial number in the IDENTIFY every boot. The patch below fixes the resume simply clearing the serial number. The proper fix would be probably to fill in the serial number of the RAID volume instead. I assume that there must be something like that stored on the drives but I don't know where. Fix resume on pata_it821x RAID volume by clearing the serial number in IDENTIFY data, which is otherwise different on each boot.

2009-02-25ide: fix refcounting in device driversBartlomiej Zolnierkiewicz
During host driver module removal del_gendisk() results in a final put on drive->gendev and freeing the drive by drive_release_dev(). Convert device drivers from using struct kref to use struct device so device driver's object holds reference on ->gendev and prevents drive from prematurely going away. Also fix ->remove methods to not erroneously drop reference on a host driver by using only put_device() instead of ide*_put().

2009-02-25atiixp: fix missing parenthesesRoel Kluin
Fix missing parentheses so PIO/DMA timings for master device on the second channel are programmed correctly (IOW "8 0 24 16" offset values should be used instead of the current "8 0 16 16"). [ The bug went unnoticed because after PIO/DMA timings get programmed incorrectly for the third device they are overwritten with timings for the fourth device and since BIOS should also program timings for the third device everything should work fine until suspend/resume cycle or user requested transfer mode changes. ] Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: Andrew Morton <akpm@linux-foundation.org> [bart: update patch description] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2009-02-25ide: ide.c 'clear' fix, update "ide=nodma" documentationDavid Fries
Documentation/kernel-parameters.txt - ide=nodma is no longer valid. drivers/ide/Kconfig - The module is ide-core.ko not ide. drivers/ide/ide.c - It took me a while to figure out what the arguments %d.%d:%d to nodma module parameter ment, so I added a comment to each. - Added a comment to each of the sscanf lines. - There is a bug, if j is 0 it would previously clear all the other bits except the current device, changed in three different places. mask &= (1 << i) should be mask &= ~(1 << i).
