Would that bring something more than what is currently present? I've set
PINCTRL_NOMADIK to select GPIO_NOMADIK. This means that if
PINCTRL_NOMADIK=3Dy then GPIO_NOMADIK=3Dy. If PINCTRL_NOMADIK=3Dn then
GPIO_NOMADIK is free to be whatever.

This behavior sounds similar to what would happen if adding "default
PINCTRL_NOMADIK".

Thanks,
