I submitted the same fix:
https://lore.kernel.org/imx/d718ddd2-d473-4455-b21a-15024e46787c@roeck-us.net/T/#mc71dc21d99e0b013c5ce46c0d90940fd8806ae9a
but as Guenter pointed out, there are other defconfigs that select
ARCH_MXC, so this change is incomplete.
It will also cause regressions for people that have their own
defconfigs (where PINCTRL is not selected).
Then I came up with a v2 that simply re-select PINCTRL as a minimal
fix for the regressions:
