2015-08-08xhci: xHCI 1.1: Stopped - Short Packet Capability (SPC)Lu Baolu3-5/+47
This patch enables xhci driver to support SPC by handling Stopped - Short Packet event in transfer event path. If SPC = '1' and the stop endpoint command is executed, after a Short Packet condition has been detected, but before the end of the TD has been reached, (i.e. the TD is in progress for pipe), then a Transfer Event TRB with its Completion Code set to Stopped - Short Packet and its TRB Transfer Length set to value of the EDTLA shall be forced for the interrupted TRB, irrespective of whether its IOC or ISP flags are set. This Transfer Event TRB will precede the Command Completion Event TRB for the command, and is referred to as a Stopped Transfer Event.

2015-08-08xhci: xHCI 1.1: Contiguous Frame ID Capability (CFC)Lu Baolu3-13/+187
If the Contiguous Frame ID Capability is supported (CFC = 1), then the xHC shall match the Frame ID in every Isoch TD with SIA = 0 against the Frame Index of the MFINDEX register. This rule ensures resynchronization of Isoch TDs even if some are dropped due to Missed Service Errors or Stopping the endpoint. This patch enables xHCI driver to support CFC by calculating and setting the Frame ID field of an Isoch TRB.

2015-08-08usb: xhci: make USB_XHCI_PLATFORM selectableRafał Miłecki1-1/+8
Right now xhci-plat-hcd can be built when using one of platform specific drivers only (mvebu/rcar). There shouldn't be such limitation as some platforms may not require any quirks and may want to just use a generic driver ("generic-xhci" / "xhci-hcd").

2015-08-06usb: musb: cppi41: allow it to work againFelipe Balbi1-3/+3
since commit 33c300cb90a6 ("usb: musb: dsps: don't fake of_node to musb core") we have been preventing CPPI 4.1 from probing due to NULL of_node. We can't revert said commit otherwise a different regression would show up, so the fix is to look for the parent device's (glue layer's) of_node instead, since that's the thing which is actually described in DTS.

Commit fb91cddc54e7 ("usb: musb: Remove DMA ifdef for musb_gadget.c short_packet") tried to remove DMA ifdeferry from musb_gadget.c but ended up leaving some around.

This header file contains helpers for quirks based on UDC controller name.

When using OF defined controllers the platform data struct is shared between all devices, so it can't be used for device specific settings.

2015-08-04usb: gadget: epautoconf: remove ep and desc configuration from ep_matches()Robert Baldyga1-32/+34
As function ep_matches() is used to match endpoint with usb descriptor it's highly unintuitive that it modifies endpoint and descriptor structures fields. This patch moves code configuring ep and desc from ep_matches() to usb_ep_autoconfig_ss(), so now function ep_matches() does nothing more than its name suggests.
