2011-12-12USB: ci13xxx_udc: handle controllers with less than 16 EPsMarc Kleine-Budde2-3/+15
The ci13xxx_udc driver checks the number of endpoints in the udc controller, however some routines expect that the hardware has 16 bidirectional endpoints. This patch improves the driver to work on controllers with less than 16 endpoints like the udc controller found on freescale's mx23 and mx28.

2011-12-01Revert "xHCI: reset-on-resume quirk for NEC uPD720200"Sarah Sharp1-6/+1
This reverts commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa. The commit added a reset-on-resume quirk because the NEC chipset stopped responding to commands about 30 minutes after a system resume from suspend. We thought it was a chipset issue, but it turns out that the xHCI driver was zeroing out the link TRB after a successful context restore during resume. The host controller would fall off the command ring sometime later, causing it to not respond to new commands. The link TRB issue has been fixed with commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 "xHCI: fix bug in xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's not necessary. Commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa was marked for stable trees back to 2.6.37, but according to my mail, it has not made it into Linus' tree or the stable trees yet.

2011-12-01xHCI: fix bug in xhci_clear_command_ring()Andiry Xu1-1/+4
When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

2011-11-29usb: musb: PM: fix context save/restore in suspend/resume pathKevin Hilman1-6/+0
Currently the driver tries to save context in the suspend path, but will cause an abort if the device is already runtime suspended. This happens, for example, if MUSB loaded/compiled-in, in host mode, but no USB devices are attached. MUSB will be runtime suspended, but then attempting a system suspend will crash due to the context save being attempted while the device is disabled. On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be called late in the suspend path (by the PM domain layer) if the driver is not already runtime suspended, ensuring a full shutdown. Therefore, the context save is not needed in the ->suspend() method since it will be called in the ->runtime_suspend() method anyways (similarily for resume.) NOTE: this leaves the suspend/resume methods basically empty (with some FIXMEs and comments, but I'll leave it to the maintainers to decide whether to remove them.

Fix for ftdi_set_termios() glitching output ftdi_set_termios() is constantly setting the baud rate, data bits and parity unnecessarily on every call, . When called while characters are being transmitted can cause the FTDI chip to corrupt the serial port bit stream output by stalling the output half a bit during the output of a character. Simple fix by skipping this setting if the baud rate/data bits/parity are unchanged.

I think the issue is that XON/XOFF flow control was being implmented via hardware - for the ixoff to allow the user to use XON/XOFF to control output. Unfortunately it would send 3 Control URBs updating all of the settings after each piece of input I am trying to work around the issue of gmail messing with the tab/spacing by submitting via SMTP via gmail which I believe should fix the issue.

2011-11-18OHCI: final fix for NVIDIA problems (I hope)Alan Stern4-64/+28
Problems with NVIDIA's OHCI host controllers persist. After looking carefully through the spec, I finally realized that when a controller is reset it then automatically goes into a SUSPEND state in which it is completely quiescent (no DMA and no IRQs) and from which it will not awaken until the system puts it into the OPERATIONAL state. Therefore there's no need to worry about controllers being in the RESET state for extended periods, or remaining in the OPERATIONAL state during system shutdown. The proper action for device initialization is to put the controller into the RESET state (if it's not there already) and then to issue a software reset. Similarly, the proper action for device shutdown is simply to do a software reset. This patch (as1499) implements such an approach. It simplifies initialization and shutdown, and allows the NVIDIA shutdown-quirk code to be removed.

2011-11-15usb-storage: Accept 8020i-protocol commands longer than 12 bytesAlan Stern1-4/+3
The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands; shorter commands must be padded. Simon Detheridge reports that his 3-TB USB disk drive claims to use the 8020i protocol (which is normally meant for ATAPI devices like CD drives), and because of its large size, the disk drive requires the use of 16-byte commands. However the usb_stor_pad12_command() routine in usb-storage always sets the command length to 12, making the drive impossible to use. Since the SFF-8020i specification allows for 16-byte commands in future extensions, we may as well accept them. This patch (as1490) changes usb_stor_pad12_command() to leave commands larger than 12 bytes alone rather than truncating them.

2011-11-15USB: cdc-acm: Fix disconnect() vs close() raceHavard Skinnemoen1-3/+5
There's a race between the USB disconnect handler and the TTY close handler which may cause the acm object to be freed while it's still being used. This may lead to things like http://article.gmane.org/gmane.linux.usb.general/54250 and https://lkml.org/lkml/2011/5/29/64 This is the simplest fix I could come up with. Holding on to open_mutex while closing the TTY device prevents acm_disconnect() from freeing the acm object between acm->port.count drops to 0 and the TTY side of the cleanups are finalized.

2011-11-15USB: EHCI: fix HUB TT scheduling issue with iso transferThomas Poussevin1-5/+10
The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. The IN iso stream can only start on the first uframe (0-2 for a 165 us) because of CSPLIT transactions. For the OUT iso stream there no such restriction. uframe 0-5 are possible. The idea of this patch is that the first uframe are precious (for IN TT iso stream) and we should allocate the last uframes first if possible. For that we reverse the order of uframe allocation (last uframe first). Here an example : hid interrupt stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- There no place for iso IN stream (uframe 0-2 are used) and we got "cannot submit datapipe for urb 0, error -28: not enough bandwidth" error. With the patch this become. iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- iso IN stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 125 | 40 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- Signed-off-by: Matthieu Castet <matthieu.castet@parrot.com> Signed-off-by: Thomas Poussevin <thomas.poussevin@parrot.com> Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-11-15USB: XHCI: resume root hubs when the controller resumesAlan Stern1-15/+14
This patch (as1494) fixes a problem in xhci-hcd's resume routine. When the controller is runtime-resumed, this can only mean that one of the two root hubs has made a wakeup request and therefore needs to be resumed as well. Rather than try to determine which root hub requires attention (which might be difficult in the case where a new non-SuperSpeed device has been plugged in), the patch simply resumes both root hubs. Without this change, there is a race: The controller might be put back to sleep before it can activate its IRQ line, and the wakeup condition might never get handled. The patch also simplifies the logic in xhci_resume a little, combining some repeated flag settings into a single pair of statements.

2011-11-15USB: workaround for bug in old version of GCCAlan Stern1-4/+3
This patch (as1491) works around a bug in GCC-3.4.6, which is still supposed to be supported. The number of microseconds in the udelay() call in quirk_usb_disable_ehci() is fixed at 100, but the compiler doesn't understand this and generates a link-time error. So we replace the otherwise unused variable "delta" with a simple constant 100. This same pattern is already used in other delay loops in that source file.
