Ah, thanks for the pointer. It might be the case. I noticed that, when
using arch/arm64/defconfig and disabling all platforms despite ARCH_MXC
before running make olddefconfig, CONFIG_PINCTRL gets disabled as well.
No platform is enabling it. I noticed this when building in yocto and
non-IMX platforms are disabled for build time reasons.

Best regards,
Alexader
