Oh, hang on - that's what you mean by a regulator object...   I don't
think this fixes the problem you think it does.  What is the actual
problem you're trying to fix here?  The min_uV and max_uV on a consumer
struct are supposed to be the request from that consumer, they should
only be set if the consumer actually made a request for a voltage range.

Why would having each individual driver open code things help?
