Thanks for working on Kirkwood. Love this platform.

select PINCTRL_KIRKWOOD too I think.
Then it's just automatic.

As stated elsewhere I think this should be
depends on PLAT_ORION

depends on ARCH_KIRKWOOD
select PINCTRL_MVEBU

I'm thinking this variant should maybe be an enum... unless it is
strongly established somewhere in Orion/Marvell stuff.

This is looking real good, clean & nice.

No further comments on this driver.
