* Revert "powerpc/usb: fix issue of CPU halt when missing USB PHY clock"Greg Kroah-Hartman2012-03-022-10/+2
| | | | | | | | | | | | | | | | | | This reverts commit 529febeee680dc22416fca033151a5e8bc620447. To quote Dirk: This commit introduces a check for the USB PHY clock. Problem is that CTRL_PHY_CLK_VALID bit seems not to be present on all Freescale ehci implementations, at least P1022 does not have it. So this check always fails and the driver never gets loaded. So we need to revert this patch.

* usb-storage: fix freezing of the scanning threadAlan Stern2012-02-212-62/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1521b) fixes the interaction between usb-storage's scanning thread and the freezer. The current implementation has a race: If the device is unplugged shortly after being plugged in and just as a system sleep begins, the scanning thread may get frozen before the khubd task. Khubd won't be able to freeze until the disconnect processing is complete, and the disconnect processing can't proceed until the scanning thread finishes, so the sleep transition will fail. The implementation in the 3.2 kernel suffers from an additional problem. There the scanning thread calls set_freezable_with_signal(), and the signals sent by the freezer will mess up the thread's I/O delays, which are all interruptible. The solution to both problems is the same: Replace the kernel thread used for scanning with a delayed-work routine on the system freezable work queue. Freezable work queues have the nice property that you can cancel a work item even while the work queue is frozen, and no signals are needed. The 3.2 version of this patch solves the problem in Bugzilla #42730.

* xhci: Fix encoding for HS bulk/control NAK rate.Sarah Sharp2012-02-211-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | The xHCI 0.96 spec says that HS bulk and control endpoint NAK rate must be encoded as an exponent of two number of microframes. The endpoint descriptor has the NAK rate encoded in number of microframes. We were just copying the value from the endpoint descriptor into the endpoint context interval field, which was not correct. This lead to the VIA host rejecting the add of a bulk OUT endpoint from any USB 2.0 mass storage device. The fix is to use the correct encoding. Refactor the code to convert number of frames to an exponential number of microframes, and make sure we convert the number of microframes in HS bulk and control endpoints to an exponent. This should be back ported to kernels as old as 2.6.31, that contain the commit dfa49c4ad120a784ef1ff0717168aa79f55a483a "USB: xhci - fix math in xhci_get_endpoint_interval" Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Tested-by: Felipe Contreras <felipe.contreras@gmail.com> Suggested-by: Andiry Xu <andiry.xu@amd.com> Cc: stable@vger.kernel.org
* USB: Set hub depth after USB3 hub resetElric Fu2012-02-211-13/+17
| | | | | | | | | | | | | | | | | | | | | | | | The superspeed device attached to a USB 3.0 hub(such as VIA's) doesn't respond the address device command after resume. The root cause is the superspeed hub will miss the Hub Depth value that is used as an offset into the route string to locate the bits it uses to determine the downstream port number after reset, and all packets can't be routed to the device attached to the superspeed hub. Hub driver sends a Set Hub Depth request to the superspeed hub except for USB 3.0 root hub when the hub is initialized and doesn't send the request again after reset due to the resume process. So moving the code that sends the Set Hub Depth request to the superspeed hub from hub_configure() to hub_activate() is to cover those situations include initialization and reset. The patch should be backported to kernels as old as 2.6.39.

* USB: Fix handoff when BIOS disables host PCI device.Sarah Sharp2012-02-211-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some systems with an Intel Panther Point xHCI host controller, the BIOS disables the xHCI PCI device during boot, and switches the xHCI ports over to EHCI. This allows the BIOS to access USB devices without having xHCI support. The downside is that the xHCI BIOS handoff mechanism will fail because memory mapped I/O is not enabled for the disabled PCI device. Jesse Barnes says this is expected behavior. The PCI core will enable BARs before quirks run, but it will leave it in an undefined state, and it may not have memory mapped I/O enabled. Make the generic USB quirk handler call pci_enable_device() to re-enable MMIO, and call pci_disable_device() once the host-specific BIOS handoff is finished. This will balance the ref counts in the PCI core. When the PCI probe function is called, usb_hcd_pci_probe() will call pci_enable_device() again. This should be back ported to kernels as old as 2.6.31. That was the first kernel with xHCI support, and no one has complained about BIOS handoffs failing due to memory mapped I/O being disabled on other hosts (EHCI, UHCI, or OHCI).

* USB: Don't fail USB3 probe on missing legacy PCI IRQ.Sarah Sharp2012-02-143-3/+13
| | | | | | | | | | | | | | | | | | Intel has a PCI USB xhci host controller on a new platform. It doesn't have a line IRQ definition in BIOS. The Linux driver refuses to initialize this controller, but Windows works well because it only depends on MSI. Actually, Linux also can work for MSI. This patch avoids the line IRQ checking for USB3 HCDs in usb core PCI probe. It allows the xHCI driver to try to enable MSI or MSI-X first. It will fail the probe if MSI enabling failed and there's no legacy PCI IRQ. This patch should be backported to kernels as old as 2.6.32.

| | * usb: gadget: check for streams only for SS udcsSebastian Andrzej Siewior2012-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the UASP gadget fails to bind on an UDC which does not provide stream support. This is true for all udc in tree except for dummy and dwc3 since they don't support SuperSpeed. There is no need to test for the availability of stream support on those UDCs because we will never even try to use them. I think it is sane to assume that StreamSupport is always available on SuperSpeed since it is one of the key features. The host side will only allocate on SS so this part is also fine.

But in dtd_complete_irq, it does again * 2, it will deference wrong memory after scanning max_ep - 1. The another similar problem is at USB_REQ_SET_FEATURE (the pipe number should be 0 and max_ep - 1).

| | * usb: renesas: silence uninitialized variable report in usbhsg_recip_run_handle()Jesper Juhl2012-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In drivers/usb/renesas_usbhs/mod_gadget.c::usbhsg_recip_run_handle() the Coverity Prevent checker currently flags a warning about possibly uninitialized use of 'ret' i usbhsg_recip_run_handle(). It does this since it assumes we take one of the non-default branches in the switch and then subsequently take the false branch in the 'if (func)' case below. This exact scenario will never happen, but Coverity can't see that for some reason. This patch initializes 'ret' to '0' when it is declared which should shut up this report and won't really hurt - so why not? At least then it's clear that 'ret' is always initialized..

A user could e.g. bind to it to a CDC ECM interface by using the new_id and bind sysfs files. But this would fail with a 0 buffer length due to the missing descriptor.
