Subject[PATCH v2 0/3] serial: Separate RT288x/Au1xxx code into own file
Date
A non-trivial amount of RT288x/Au1xxx code is encapsulated into
ifdeffery in 8250_port / 8250_early and some if/switch UPIO_AU blocks.
Create a separate file from them and do a few additional cleanups.

I kept the Kconfig entry as bool because the code has somewhat tricky
dependency chain (mips arch code and 8250_of driver). It would be nice
to make it tristate but I don't know how blocking some invalid =m + =y
combinations would be best addressed. It should probably be best done
on top of this series independent of the split itself anyway.

UPIO_AU could now be removed because it's same as UPIO_MEM for the
remaining code path but I'm unsure if that's allowed (is the port
iotype part of stable ABI or not)?

v2:
- Define register map array lengths explicitly to avoid creating
declaration trap.

Ilpo Järvinen (3):
serial: 8250: RT288x/Au1xxx code away from core
serial: 8250_rt288x: Name non-standard divisor latch reg
serial: 8250_rt288x: Remove unnecessary UART_REG_UNMAPPED
