Yep, I got the UDC working on my SoCFPGA board. We should probably
rename the s3c-otg driver to something more fitting (dwc2-udc ?)
and strive to somehow merge the dwc2-host and dwc2-udc drivers in
the long run.

Speaking of the rename, I'd like to leave that for the next MW, to
make sure it doesn't break any tools which might for example depend
on the name of the driver.

It is :) ... it must have been hard to tell from patch 5/5 ;-)
