No, but this is for a limited subset of devices that the hardware knows
how to write to directly which means that they're restricted to things
that can be supported with regmap (or already know how to interact with
the hardware and don't need this interface at all).  The proposed patch
already relies on regmap - it's passing back the information the regmap
helpers use.

Right, drivers can say exactly which regmap to use.
