usb: patches for v4.4 merge window

This pull request is large with a total of 136 non-merge
commits. Because of its size, we will only describe the big things in
broad terms.

Many will be happy to know that dwc3 is now almost twice as fast after
some profiling and speed improvements. Also in dwc3, John Youn from
Synopsys added support for their new DWC USB3.1 IP Core and the HAPS
platform which can be used to validate it.

A series of patches from Robert Baldyga cleaned up uses of
ep->driver_data as a flag for "claimed endpoint" in favor of the new
ep->claimed flag.

Sudip Mukherjee fixed a ton of really old problems on the amd5536udc
driver. That should make a few people happy.

Heikki Krogerus worked on converting dwc3 to the unified device property
interface.

Together with these, there's a ton of non-critical fixes, typos and
stuff like that.

usb: misc: usbtest: add bulk queue test

2015-10-13T18:19:49+00:00

The bulk queue tests are used to show 'best performance' for bulk
transfer, we are often asked this question by users. The implementation
is the same with iso test, that is queue request at interrupt completion,
so we reuse the iso structures, and rename them as common one.

It's result should be very close to IC simulation, in order
to get that, the device side should also need to prepare enough
queue.

We have got the 'best performance' (IN: 41MB, OUT: 39MB) at i.mx platform
(USB2, ARM Cortex A9, stream mode need to enable) with below command:

Host side:
modprobe usbtest
./testusb -a -t 27 -g 64 -s 16384
./testusb -a -t 28 -g 64 -s 16384
Gadget side:
modprobe g_zero loopdefault=1 qlen=64 buflen=16384

usb: misc: usbtest: format the data pattern according to max packet size

2015-09-27T15:54:31+00:00

With this change, the host and gadget doesn't need to agree with transfer
length for comparing the data, since they doesn't know each other's
transfer size, but know max packet size.

usb: misc: usbtest: delete useless memset for urbs array

The element of urbs array will be initialized at below code
at once.

	for (i = 0; i < param->sglen; i++) {
		urbs[i] = iso_alloc_urb(udev, pipe, desc,

usb: misc: usbtest: format max packet size for iso transfer

2015-08-18T17:05:23+00:00

The current code prints all wMaxPacketSize content at endpoint
descriptor, if there is a high speed, high bandwidth endpoint,
it may confuse the users, eg, if there are 3 transactions during
microframe, it will print "wMaxPacket 1400" for packet content.
This commit splits wMaxpacketSize and transaction numbers for
output messages.
