Sorry for not mentioning that (not intentional). So, I'll push out V2 of the
pinctrl and gpio drivers incorporating all review comments. If that looks
good then we can work on adding S500 support on top of it.

Otherwise we can look on integrating S900 pinctrl definitions with your base
driver. Anyway, for making it easier for comparing both drivers, are you going
to submit yours?
