Series dwc3 dependencies for HiKey960 USB | expand

Just wanted to send these out again to try to make some progress
on these patches originally by Yu Chen to get HiKey960
dev-board's USB functionality working.

For now I've dropped the hub switching functionality from the
series, as I've not yet been able to come up with a solution to
Rob's objections. So this set focuses just on the dwc3 changes

The full patchset (including hub switching and dts changes not
submitted here) can be found here:

I'd greatly appreciate any feedback or thoughts!


New in v8:
* Rob objected to the custom hub switching logic in the
  previous series, so I've dropped it for now.
