I think it might be best to allocate a dynamic tty major nowdays

Other problem is that I don't see where you hold the port lock over all
uses of port->tty. That is an assumption of the serial layer and done in
the original 8250 driver correctly.

Rest looks good and I agree that OMAP is different enough from 8250 that
it makes sense not to further clutter the 8250 driver.
