Hi,
An earlier series[1] tried to implement bindings for PM domain performance states. Rob Herring suggested that we can actually write the supporting code first instead of bindings, as that will make things easier to understand for all.
The bindings [1] aren't discarded yet and this series is based on a version of those only. The bindings are only used by the last patch, which should not be applied and is only sent for completeness.
All other patches can be reviewed/applied whenever the maintainers feel they look good.
A brief summary of the problem this series is trying to solve:
Some platforms have the capability to configure the performance state of their Power Domains. The performance levels are represented by positive integer values, a lower value represents lower performance state.
We decided earlier that we should extend Power Domain framework to support active state power management as well. The power-domains until now were only concentrating on the idle state management of the device and this needs to change in order to reuse the infrastructure of power domains for active state management.
The first 5 patches update the PM domain and QoS frameworks to support that and the last one presents the front end interface to it.
All the patches are tested by hacking the OPP core a bit for now.
