Thanks, that works for me. So for v2:

- drivers/tty/serial/cortina-uart.c, SERIAL_CORTINA,
  SERIAL_CORTINA_CONSOLE;
- the CS75xx parts keep the existing "cortina" prefix
  ("cortina,cs7542-uart"), the CA parts get "cortina-access,<soc>-uart"
  when they are added;
- the binding and the Kconfig help name both families, as "Cortina
  Systems CS75xx" and "Cortina Access CAxxxx".

Arnd, this also answers the prefix question from patch 4 for me: I
would leave the CS75xx compatibles and the dts directory on "cortina"
then, and use "cortina-access" only for the parts that Cortina Access
made. Please shout if you or the DT maintainers see it differently.

Thanks,
