It might be the case. >=20 > The goal of the patch mentioned above was to be able to build a kernel > for LS1021A without pinctrl framework enabled, as LS1021A does not have > a pinctrl driver. >=20 > With your patch, that would not be possible anymore. Why? LS1021A is arm, not arm64 which this patch is touching only. BTW: Commit b77bd3ba762f3 ("ARM: imx: Re-introduce the PINCTRL selection") is actually doing the same for arm as there is some fallout from 17d21001891402. > > 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.

PINCTRL is crucial for any SoC to even boot, so this is an option which has to be set if that platform is enabled.
