Looks good in general..

But this you should not need. I know tusb6010 is
still doing that, but you can pass it in the platform_data
and then there's no need to export it.

Then in your driver you can do:

if (xxxxx->retime)
	xxxxx->retime(123);

That way the driver will stay generic. The set_power
functions are doing that in drivers/usb/musb if you
need examples.

Also, this will need a slight update based on Adrian Hunter's
patch "OMAP2/3: GPMC: put sync_clk value in picoseconds
instead of nanosecond" that I'll be queuing.

Regards,

Tony
