Do you mean passing through the uart_port? Yes, that seems sensible.
Depending on how complicated the callbacks are, it might be
simpler to write a new platform_driver based on of_serial.c for
your device that hardcodes these.
The of_serial driver started out with the goal of covering all sorts
of serial port devices based on device tree probing, but with the
direction that the platform drivers have moved to, this seems a bit
silly, and I think we should take the NWPSERIAL support out and
rename it to 8250_of.c.
