Thank you.

I have a question regarding defining regulators.

In case when drivers expect regulators to be define, but physically chips are just wired to VCC (or to 
some non-programmable power logic), what is the policy regarding regulator-fixed objects?

Shall we define per-consumer regulator-fixed objects?
Or have a single regulator-fixed for each voltage?
Or not define regulators at all and let the code to create dummy regulators?
Or something else?
