So, file or files? :D

This should have been

pinctrl-n
pinctrl-names

I made a mistake in my lenovo dts if that was your reference..

You should also mention that the implicit removal of sdhci1's
gpio properties from the lenovo j606f and oneplus billie2 is intentional
as they both use UFS instead of eMMC.

And one more thing, you missed bringing the CD pin back into pinctrl-0/1
in the tab dts. I'd really appreciate if you could fix up that ordering
mess I mentioned above while at it.
