MC13783_REG_POWERMISC_PWGTSPI_M as I don't understand it's purpose
without going through mc13783_reg_rmw_powermisc (which I didn't do yet).

What is the base for your patch?  (Hm, it seems next could work.
mc13783-regulator seems to have gotten some more #defines ending in _M.
You seem to mean "mask".  IMHO it's a bit unfortunate, because the
nameing scheme doesn't match the already existing names :-()

Shouldn't mc13783_state_powermisc_pwgt be a per-device variable instead
of a static variable?

Best regards
Uwe
