Subject: [PATCH 0/3] serial: Separate RT288x/Au1xxx code into own file
Date: Fri, 30 Dec 2022 13:46:00 +0200 [thread overview]
Message-ID: <20221230114603.16946-1-ilpo.jarvinen@linux.intel.com> (raw)
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)?
