Does FSD have some version number? The FDS, especially in compatibles,
looks quite generic, so what will happen if a newer SoC comes later? You
would have:
 - tesla,fsd-pinctrl
 - tesla,fsd-xxxx-pinctrl (where xxxx could be some new version)

This will be extra confusing, because fsd-pinctrl looks like the generic
one, while it is specific...

Best regards,
