My first question would be why do this at the regmap helper level, why not do this at the core level by stepping through selectors? I'd also expect to be programming the step size here, while some regulators aren't able to regulate well over larger step changes I'd expect that they wouldn't need to step through every single possible voltage value, that's potentially extremely slow.

Please just write normal conditional statements so the code is more readable and hence maintainable. [unhandled content-type:application/pgp-signature] | |
