I've had a quick look at the code, the regmap is passed through platform data 
to the subdevices. With such an approach I could even pass the lock down to 
the regulator driver (not that it would be a good idea of course).

I'll push the code as-is for now, but I'll this in mind when migrating the PFC 
driver to regmap.
