As expected I'm happy with this patch now. If you respin, consider
adding a comment to .request() describing the effect of the register
access there. I guess it's about pinmux, so something like:
/* Configure the XYZ pin as PWM output */
(with XYZ replaced by something sensible of course).
It's fine for me if this patch gets in via MFD as suggested in the cover
letter.
