Good!

select PINCTRL_MVEBU simply?

And then have the Armada Kconfig

select PINCTRL
select PINCTRL_ARMADA_370

This machine doesn't seem to depend in the MVEBU driver, I guess it's
the same ARCH as something else, oh well. Still suspect the
MVEBU driver should depend on PLAT_ORION until proven
wrong.

Shouldn't this be a #defined thing or something. "variant 0" doesn't
tell me much.

No further comments, looking good.
