It makes sense to tag the existing state with the context loss
information as otherwise we'll be duplicating the state in the
pinctrl driver potentially for hundreds of pins.

Maybe this patch description should clarify that it's the
pinctrl device restoring the pin state, not the pinctrl
consumer devices?

So maybe just "a pinctrl device needs to force apply a state"
instead of just device above?
