I'm not sure this is a right portion of the top.
This one is based on 8250_pci.c apparently.

The point of splitting is to get rid of code that is not used. Do you
have UPIO_PORT case?

Those are not needed anymore. This is the point of split. Check how it
was done for 8250_mid.c and/or 8250_lpss.c.

Similar here. It might be reduced.

No need to copy'n'paste everything. Just minimize your stuff to do
exactly what is needed. I'm pretty sure you copied a lot of legacy
from 8250_pci.c.
Consider to reduce this module approximately twice by LOC.
