Bjorn's latest patchset does break Gobi 1K and 2K because on both devices as it claims usb interface 0. That's because usbif 0 is not handled in the switch statement, and thus the if0 gets claimed when it should not. So let's just make things even simpler yet, and handle both the 1K and 2K+ cases separately. This patch should not affect the new Sierra device support, because those devices are matched via interface-specific matching and thus should never hit the composite code. Signed-off-by:

This patch fixes an issue introduced by patch: 72c973dd usb: gadget: add usb_endpoint_descriptor to struct usb_ep Without this patch we see a kworker taking 100% CPU, after this sequence: - Connect gadget to a windows host - load g_ether - ifconfig up <ip>; ifconfig down; ifconfig up - ping <windows host> The "ifconfig down" results in calling eth_stop(), which will call usb_ep_disable() and, if the carrier is still ok, usb_ep_enable(): usb_ep_disable(link->in_ep); usb_ep_disable(link->out_ep); if (netif_carrier_ok(net)) { usb_ep_enable(link->in_ep); usb_ep_enable(link->out_ep); } The ep should stay enabled, but will not, as ep_disable set the desc pointer to NULL, therefore the subsequent ep_enable will fail. This leads to permanent rescheduling of the eth_work() worker as usb_ep_queue() (called by the worker) will fail due to the unconfigured endpoint. We fix this issue by saving the ep descriptors and re-assign them before usb_ep_enable().

Existing implementation of tegra_ehci_remove() calls usb_put_hcd(hcd) first and then iounmap(hcd->regs). usb_put_hcd() implementation calls hcd_release() which frees up memory allocated for hcd. As iounmap is trying to unmap hcd->regs, after hcd getting freed up, warning messages were observed during unload of USB. Hence fixing it. Signed-off-by:

We cannot unconditionally access any usb-serial port specific data from the interface driver. Both supending and resuming may happen after the port has been removed and portdata is freed. Treat ports with no portdata as closed ports to avoid a NULL pointer dereference on resume. No need to kill URBs for removed ports on suspend, avoiding the same NULL pointer reference there.

Some usb-serial drivers may access port data in their suspend/ resume functions. Such drivers must always verify the validity of the data as both suspend and resume can be called both before usb_serial_device_probe and after usb_serial_device_remove. But the port data may be invalidated during port_probe and port_remove. This patch prevents the race against suspend and resume by disabling suspend while port_probe or port_remove is running.

Doing port specific cleanup in the .port_remove hook is a lot simpler and safer than doing it in the USB driver .release or .disconnect methods. The removal of the port from the usb-serial bus will happen before the USB driver cleanup, so we must be careful about accessing port specific driver data from any USB driver functions. This problem surfaced after the commit 0998d063 device-core: Ensure drvdata = NULL when no driver is bound which turned the previous unsafe access into a reliable NULL pointer dereference.

Since commit "5e0aa49e usb: chipidea: use generic map/unmap routines", the udc part of the chipidea driver needs the generic usb gadget helper functions. If the chipidea driver with udc support is built into the kernel and usb gadget is built a module, the linking of the kernel fails with: drivers/built-in.o: In function `_hardware_dequeue': drivers/usb/chipidea/udc.c:527: undefined reference to `usb_gadget_unmap_request' drivers/usb/chipidea/udc.c:1269: undefined reference to `usb_gadget_unmap_request' drivers/usb/chipidea/udc.c:1821: undefined reference to `usb_del_gadget_udc' drivers/usb/chipidea/udc.c:443: undefined reference to `usb_gadget_map_request' drivers/usb/chipidea/udc.c:1774: undefined reference to `usb_add_gadget_udc' This patch changes the dependencies, so that udc support can only be activated if the linux gadget support (USB_GADGET) is builtin or both chipidea driver and USB_GADGET are modular. Same dependencies for the chipidea host support and the linux host side USB support (USB). While there, fix the indention of chipidea the help text.

Merge tag 'for-usb-linus-2012-08-09' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-linus Intel xhci: Work around immediate reboot on shutdown. Hi Greg, I'm cleaning out my queue before I leave on vacation tomorrow, so here's one more patch for 3.6. It works around an issue on a couple Intel Panther Point desktop systems that cause them to reboot about 10 seconds after the user shutdowns the system. Sarah Sharp

Sarah Sharp authored
The Intel desktop boards DH77EB and DH77DF have a hardware issue that can be worked around by BIOS. If the USB ports are switched to xHCI on shutdown, the xHCI host will send a spurious interrupt, which will wake the system. Some BIOS will work around this, but not all. The bug can be avoided if the USB ports are switched back to EHCI on shutdown. The Intel Windows driver switches the ports back to EHCI, so change the Linux xHCI driver to do the same. Unfortunately, we can't tell the two effected boards apart from other working motherboards, because the vendors will change the DMI strings for the DH77EB and DH77DF boards to their own custom names. One example is Compulab's mini-desktop, the Intense-PC. Instead, key off the Panther Point xHCI host PCI vendor and device ID, and switch the ports over for all PPT xHCI hosts. The only impact this will have on non-effected boards is to add a couple hundred milliseconds delay on boot when the BIOS has to switch the ports over from EHCI to xHCI. This patch should be backported to kernels as old as 3.0, that contain the commit 69e848c2 "Intel xhci: Support EHCI/xHCI port switching." Signed-off-by:

Most are marked for stable as well. The first one makes the xHCI driver load properly on newer Rensas hosts. The next two fix issues with the Etron host incorrectly marking short transfers as successful, and avoiding log warning spam for hosts that make the same mistake. The last patch fixes a really nasty xHCI driver bug that could cause general protection faults when devices stall transfers. Sarah Sharp

This patch fixes a particularly nasty bug that was revealed by the ring expansion patches. The bug has been present since the very beginning of the xHCI driver history, and could have caused general protection faults from bad memory accesses. The first thing to note is that a Set TR Dequeue Pointer command can move the dequeue pointer to a link TRB, if the canceled or stalled transfer TD ended just before a link TRB. The function to increment the dequeue pointer, inc_deq, was written before cancellation and stall support was added. It assumed that the dequeue pointer could never point to a link TRB. It would unconditionally increment the dequeue pointer at the start of the function, check if the pointer was now on a link TRB, and move it to the top of the next segment if so. This means that if a Set TR Dequeue Point command moved the dequeue pointer to a link TRB, a subsequent call to inc_deq() would move the pointer off the segment and into la-la-land. It would then read from that memory to determine if it was a link TRB. Other functions would often call inc_deq() until the dequeue pointer matched some other pointer, which means this function would quite happily read all of system memory before wrapping around to the right pointer value. Often, there would be another endpoint segment from a different ring allocated from the same DMA pool, which would be contiguous to the segment inc_deq just stepped off of. inc_deq would eventually find the link TRB in that segment, and blindly move the dequeue pointer back to the top of the correct ring segment. The only reason the original code worked at all is because there was only one ring segment. With the ring expansion patches, the dequeue pointer would eventually wrap into place, but the dequeue segment would be out-of-sync. On the second TD after the dequeue pointer was moved to a link TRB, trb_in_td() would fail (because the dequeue pointer and dequeue segment were out-of-sync), and this message would appear: ERROR Transfer event TRB DMA ptr not part of current TD This fixes bugzilla entry 4333 (option-based modem unhappy on USB 3.0 port: "Transfer event TRB DMA ptr not part of current TD", "rejecting I/O to offline device"), https://bugzilla.kernel.org/show_bug.cgi?id=43333 and possibly other general protection fault bugs as well. This patch should be backported to kernels as old as 2.6.31. A separate patch will be created for kernels older than 3.4, since inc_deq was modified in 3.4 and this patch will not apply.

All on the MUSB driver and quite obvious. First there's a Kconfig change which was missed earlier, then there is a fix for the usage of the resource name and lastly a fix for pm_runtime usage and device initialization. The last fix is rather critical as it can end up in situations where we try to access device's register with clocks disabled, which will cause a Data Abort exception (on ARM).

Gary reports that with recent kernels, he notices more xHCI driver warnings: xhci_hcd 0000:03:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? We think his Etron xHCI host controller may have the same buggy behavior as the Fresco Logic xHCI host. When a short transfer is received, the host will mark the transfer as successfully completed when it should be marking it with a short completion. Fix this by turning on the XHCI_TRUST_TX_LENGTH quirk when the Etron host is discovered. Note that Gary has revision 1, but if Etron fixes this bug in future revisions, the quirk will have no effect. This patch should be backported to kernels as old as 2.6.36, that contain a backported version of commit 1530bbc6 "xhci: Add new short TX quirk for Fresco Logic host." Signed-off-by:

OLPC machines are now ARM-based (which means lots of x86 and ARM changes), but are typically pretty self-contained.. so it makes more sense to go through a separate OLPC tree after getting the appropriate review/ACKs." * 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc: x86: OLPC: move s/r-related EC cmds to EC driver Platform: OLPC: move global variables into priv struct Platform: OLPC: move debugfs support from x86 EC driver x86: OLPC: switch over to using new EC driver on x86 Platform: OLPC: add a suspended flag to the EC driver Platform: OLPC: turn EC driver into a platform_driver Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it drivers: OLPC: update various drivers to include olpc-ec.h Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver

Pull arm-soc Marvell Orion device-tree updates from Olof Johansson: "This contains a set of device-tree conversions for Marvell Orion platforms that were staged early but took a few tries to get the branch into a format where it was suitable for us to pick up. Given that most people working on these platforms are hobbyists with limited time, we were a bit more flexible with merging it even though it came in late." * tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: Kirkwood: Replace mrvl with marvell ARM: Kirkwood: Describe GoFlex Net LEDs and SATA in DT.

Pull arm-soc cpuidle enablement for OMAP from Olof Johansson: "Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but didn't go in because the pull request ended up rejected. So it just got merged, and we got this staged branch that enables the coupled cpuidle code on OMAP. With a stable git workflow from the other maintainer we could have staged this earlier, but that wasn't the case so we have had to merge it late. The alternative is to hold it off until 3.7 but given that the code is well-isolated to OMAP and they are eager to see it go in, I didn't push back hard in that direction." * tag 'pm2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: OMAP4: CPUidle: Open broadcast clock-event device. ARM: OMAP4: CPUidle: add synchronization for coupled idle states ARM: OMAP4: CPUidle: Use coupled cpuidle states to implement SMP cpuidle. ARM: OMAP: timer: allow gp timer clock-event to be used on both cpus
