Sorry for being extremely late in reviewing this stuff. You are
already on v3 and I haven't reviewed it once. Mostly due to bad timing
of my holidays and other work pressure.

Now, there are few things that I feel are not properly addressed here,
and I may be wrong:
- Where are the bindings for static-power-points and
  dynamic-power-coefficient. Sorry I failed to see them in this or
  other series you mentioned.
- Even then, why should we be adding another table into DT for
  voltage/power ? And not reuse and extend the opp-v2 stuff which is
  already mainlined now.
- There are few issues with the code as well, but I want to see where
  the bindings should go first. And then only discuss the code
  further.
