Just a quick notice here... calling the driver as "dwc" sounds confusing,
we have already a "dwc2" and a "dwc3" driver (and an OOT "otg-dwc" driver
at RPi tree).

Ok, those are USB drivers, but, as we had some patches for it (or due
to it) at linux-media, I would prefer if you could use some other name
here, to avoid confusion :-)

Thanks,
Mauro
