Subject: [PATCH v4 0/9] Prereqs for HiKey960 USB support

Just another round here trying to push forward a patch series
submitted previously by Yu Chen to get HiKey960 dev-board's USB
functionality working.

This series focuses on just the dwc3 changes and bindings
needed.

The current full patchset can be found here:
  https://git.linaro.org/people/john.stultz/android-dev.git/log/?id=ce013895404bd4a5b6487df0ac30ed2dbea43f5d

NOTE: I unfortunately don't have any deep knowledge of the
hardware other then the previously submitted code  and what I
can intuit from testing, but I tried to document the previously
undocumented bindings as best I could, fixed up a few minor
checkpatch issues and tried to address previous feedback as best
I could.

I'd greatly appreciate any feedback or thoughts!

thanks
-john
