I will be more than happy to get that in.

Thanks.

Do you think its a good time to get some bindings for this stuff now? The
bindings would be required for only users and not PM domains themselves for now.
Users are:

- OPP core: need per-OPP entry value for performance state.
- Devices: devices directly using the PM domain without OPP core (don't have
  DVFS). They can use the same property.

It might look similar to the properties I initially started with, I can just get
them refreshed.
