* usb: usbtest: add pattern check on pipe in phase of unlink readHuang Rui2014-05-281-0/+3
| | | | | | | | | | | TEST 11 unlinks the URB read request for N times. When host and gadget both initialize pattern 1 (mod 63) data series to do IN transfer, the host side function should check the data buffer if it is as mod 63 series, because the data packet which host receivced will follow pattern 1. So this patch adds this checking action. Signed-off-by: Huang Rui <ray.huang@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* usb: usbtest: fix unlink write error with pattern 1Huang Rui2014-05-281-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TEST 12 and TEST 24 unlinks the URB write request for N times. When host and gadget both initialize pattern 1 (mod 63) data series to transfer, the gadget side will complain the wrong data which is not expected. Because in host side, usbtest doesn't fill the data buffer as mod 63 and this patch fixed it.

* usb: usb5303: add support for reference clock specified in device treeMarek Szyprowski2014-05-281-2/+57
| | | | | | | | | | | | | USB3503 chip supports 8 values of reference clock. The value is specified by REF_SEL[1:0] pins and INT_N line. This patch add support for getting 'refclk' clock, enabling it and setting INT_N line according to the value of the gathered clock. If no clock has been specified, driver defaults to the old behaviour (assuming that clock has been specified by REF_SEL pins from primary reference clock frequencies table).

Happy Holidays, Greg! Here's four patches to be queued to usb-next for 3.14. One adds a module parameter to the xHCI driver to allow users to enable xHCI quirks without recompiling their kernel, which you've already said is fine. The second patch is a bug fix for new usbtest code that's only in usb-next. The third patch is simple cleanup. The last patch is a non-urgent bug fix for xHCI platform devices. The bug has been in the code since 3.9. You've been asking me to hold off on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and be backported to stable once 3.14 is out. These have all been tested over the past week. I did run across one oops, but it turned out to be a bug in 3.12, and therefore not related to any of these patches. Please queue these for usb-next and 3.14. Thanks, Sarah Sharp
| * usbtest: Fix BOS control test for USB 2.01 devices.Sarah Sharp2013-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit c952a8ba7136505cd1ca01735cc748ddc08c7d2f "usb: usbtest: add a test case to support bos for queue control" will cause USB 2.01 and USB 2.10 devices with a BOS descriptor to fail case 15 of the control test. The Link PM errata (released in 2007, updated in 2011) says: "The value of the bcdUSB field in the standard USB 2.0 Device Descriptor is used to indicate that the device supports the request to read the BOS Descriptor (i.e. GetDescriptor(BOS)). Devices that support the BOS descriptor must have a bcdUSB value of 0201H or larger." The current code says that non-SuperSpeed devices *must* return -EPIPE, as this comment shows: /* sign of this variable means: * -: tested code must return this (negative) error code * +: tested code may return this (negative too) error code */ int expected = 0; This means the test will fail with USB 2.01 and USB 2.10 devices that provide a BOS descriptor. Change it to only require a stall response if the USB device bcdUSB is less than 2.01. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Acked-by: Huang Rui <ray.huang@amd.com>

| | | | | | | | | | | | | | | | | | | | If the connect signal is pulled high then the device will start up meaning that if we just pull it high on probe then the device will start running prior to the configuration being written out. Fix this by pulling the GPIO low when we reset and only pulling it high when configuration is finished.

| | | | | | | | | | | | | | | | | | | | | | The intn and connect GPIO properties are swapped in the code which will cause failures at runtime if these are connected, fix the code. There are currently no in-tree users of this device to check or update.

* | USB: simplify the interface of usb_get_status()Alan Stern2013-08-011-5/+4
| | | | | | | | | | | | | | | | | | | | This patch simplifies the interface presented by usb_get_status(). Instead of forcing callers to check for the proper data length and convert the status value to host byte order, the function will now do these things itself.
