2013-08-13	usb: ehci: Add support for SINGLE_STEP_SET_FEATURE test of EHSET	Manu Gautam	1	-1/+19
	The USB Embedded High-speed Host Electrical Test (EHSET) defines the SINGLE_STEP_SET_FEATURE test as follows: 1) The host enumerates the test device with VID:0x1A0A, PID:0x0108 2) The host sends the SETUP stage of a GetDescriptor(Device) 3) The device ACKs the request 4) The host issues SOFs for 15 seconds allowing the test operator to raise the scope trigger just above the SOF voltage level 5) The host sends the IN packet 6) The device sends data in response, triggering the scope 7) The host sends an ACK in response to the data This patch adds additional handling to the EHCI hub driver and allows the EHSET driver to initiate this test mode by issuing a a SetFeature request to the root hub with a Test Selector value of 0x06. From there it mimics ehci_urb_enqueue() but separately submits QTDs for the SETUP and DATA/STATUS stages in order to insert a delay in between.

2013-07-25	usb: misc: EHSET Test Fixture device driver for host compliance	Manu Gautam	1	-0/+134
	An Embedded Host High-Speed Electrical Test (EHSET) test fixture is used to initiate test modes on a host controller in order to perform the high speed electrical testing procedure for USB-IF compliance. When this test fixture is connected to a host, it can enumerate as one of several selectable VID/PID pairs, each corresponding to one of the following test modes: * TEST_SE0_NAK * TEST_J * TEST_K * TEST_PACKET * HS_HOST_PORT_SUSPEND_RESUME * SINGLE_STEP_GET_DEV_DESC * SINGLE_STEP_SET_FEATURE The USB EHSET procedure can be found here: http://www.usb.org/developers/onthego/EHSET_v1.01.pdf Signed-off-by: Manu Gautam <mgautam@codeaurora.org> [jackp@codeaurora.org: imported from commit 073c9409 on codeaurora.org; minor cleanup and updated author email] Signed-off-by: Jack Pham <jackp@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
