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 -john
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@intel.com>
