Subject: [RFC][PATCH 0/5] dwc3: Changes for HiKey960 support

I've been carrying for awhile some patches that Yu Chen was
previously pushing upstream to enable USB on the HiKey960 board
and I wanted to try to nudge them forward as I'm not sure as to
what his plans are.

I've reviewed some of the feedback from his last series, and
tried to clean things up a little bit. However, there are still
some dt binding bits between the misc switch driver and how it
interacts with the rt1711 and dwc3 driver that I'm unsure of.

However, there were some simpler parts of the patch set that I
wanted to send out to see if we could make some progress on
those parts while I continue to work on the more complex bits.

You can find the full set of changes to get USB working on the
board here:

This series is just the more trivial changes, along with some
missing binding documentation that I've added.

I'd greatly appreciate any review or feedback on this series!

thanks
-john
