Right, that's what I'm thinking as well esp. since ULPI is a standard
(ok, kinds of) and I'm not seeing too much specialty of pxa3xx ULPI
except for the way to access registers. Cannot remember the detail
but the OTG might be a hybrid model on pxa310, and might be a
little bit different from others.
