[PATCH v6 0/8] HiKey960 USB support

From: John Stultz
Date: Thu Nov 28 2019 - 00:10:07 EST


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

The full patchset (including dts changes not submitted here) can
be found here:
https://git.linaro.org/people/john.stultz/android-dev.git/log/?id=950276ae1baab3a22836d1f89aeadbb08adf41e0


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. I tried to document the previously
undocumented bindings, 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

New in v6:
* Felipe previously had disliked extending the dwc3 binding
to allow for more flexible clock and resest lists, so in
the last series I switched back to the dwc3-simple-of.c
approach, but Rob pushed back on the last series, and with
no reply from Felipe, I've switched back to this appraoch.
Clear guidance would be appreciated here!
* Fixed build issue Reported-by: kbuild test robot <lkp@xxxxxxxxx>
