This doesn't seem great...  it doesn't seem to know or represent
anything at all about the hardware, I'd expect a voltage regulator to at
a minimum be able to implement list_voltage().  You've not provided any
information on what the hardware actually is and the driver just seems
to proxy through to some other API which actually implements the
regulator support.

This seems broken, why are you interfering with the supplied
constraints?
