Ah, thanks. Both this and the pattern above was taken from
pinctrl/mediatek,mt6779-pinctrl.yaml if anyone feels like fixing that
too. I see now that '-[0-9]+$' and '-pins$' is more common. I'll just
use that.

Right, but the common schema specifies one of boolean or uint32. Is
there a way to reference that, but still say that this binding
supports only the boolean version?
