After I read your references and thought a bit more,
I am now considering to change the bool into tristate.

Pinctrl drivers usually contain quite big pin tables, so
it sounds somewhat reasonable to make it loadable,
given that minimal pin-settings could be done in the boot-loader.
Actually, some of pinctrl drivers in the mainline are already tristate.

I will send v2 later with some other fixes I have noticed.

Is this OK with you?

Best Regards
