On various mxc boards, the intial ULPI reads resulted in a timeout

Initializing the hardware lines connected to the transceiver (through
pdata->init call) before actually enabling clocks and configuring
registers in the devices fixes this problem.
Hmm, glad to hear it fixed your problem :) However, there is no real
ULPI communication done on the viewports before the board specific
init function is called, and the timeouts that are reported come from
the transceiver probing which is called at a later point.
Even with that patch applied, one board I have here fails to initialize
the OTG port.
can you probe the DIR signal (pin 19) of the ISP1504 when you have the
problem ?
