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. Remove them so that when building kernels with all DMA engines enabled, we don't end up trying to allocte channels twice. Signed-off-by: Felipe Balbi <[email protected]>
2015-08-06usb: gadget: remove gadget_chips.hRobert Baldyga15-74/+0
This header file contains helpers for quirks based on UDC controller name. Since we have generic quirk bitfields in usb_gadget structure for all of these quirks we don't need to have this header any longer. This patch removes gadget_chips.h file and makes sure that it's no longer included anywhere in kernel sources.

Add callback that is called by epautoconf to allow UDC driver match the best endpoint for specific descriptor. It's intended to supply mechanism which allows to get rid of chip-specific endpoint matching code from epautoconf. If gadget has set 'ep_match' callback we prefer to call it first, and if it fails to find matching endpoint, then we try to use default matching algorithm.

2015-08-05usb: ehci-platform: Fix using multiple controllers from OFAlban Bedel1-4/+9
When using OF defined controllers the platform data struct is shared between all devices, so it can't be used for device specific settings. However it is currently used for the OF properties needs-reset-on-resume and has-transaction-translator. To fix this issue move setting hcd->has_tt to the probe and move pdata->reset_on_resume to the private data.

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.

Introduce endpoint matching mechanism basing on endpoint capabilities flags. We check if endpoint supports transfer type and direction requested in ep descriptor.
