Generally I agree wholeheartedly, but as we discussed,
it might not be worth the trouble in this case.

Yes, I can add that for sure !

The input subsystem is concerned with input from humans?
But in this case, it's really a power output from an external card
on a PCB assembly. Regulator seemed the kernel abstraction
closest to what this actually represents.

I'm honestly not fully satisfied by the use of the regulator
abstraction here. If you know of a different abstraction
which seems better, I'll definitely consider it.
