Yup, I've been bitten by this before on other boards. Marking the
wrong port as an EHCI port will result in 12 pads being put in the
wrong mux-mode straight away, due to the padconf settings we do in
usb-ehci.c. With 12-pads, there's a very high chance that you lose
other functionality.

The patch has my ack.

Is there a link to the schematics somewhere, so the next time we
see something like this, we can just use those as reference?
