The simplest solution would probably be completely userspace. Write a jackd client which connects to the UART, gives itself RT priority using capabilities, and exposes however many input/output ports as you have. Google FFADO for an example of the programming model used. If you need normal apps to drive into it, set up an .asoundrc with a device using the jack plugin. I still don't see why you need a kernel driver at all.
