Have a git tree to test?  Patch doesn't apply cleanly (using 4.8-rc5
with eric's for-next branch which already has 1+2), seems to depend on
more device tree changes.

Also usb is working fine for me on the rpi3 even without this, so why is
this needed?  Is dwc2 defaulting to otg mode a recent change?

cheers,
