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.
