Looking good. Comments below.
This patch also replaced the spaces between the macros and their
values
across suspend/resume?
The serial core calls your set_termios() handler upon
resume (either for the console or if a tty is open)
so you should be reprogramming the hardware there
based on the termios settings.

It may need a driver to, for example, power the device on

2) why is this tied to the tty core and not the serial core
