Subject: [PATCH v2 0/2] CPUFreq: Add support for cpu performance dependencies

Hi Rob, Rafael, Viresh, Daniel and Sudeep,

I am proposing the addition of performance dependencies in cpufreq core
and one if its drivers (the implementation/approach is RFC).
This is to support systems where exposed cpu performance controls are more
fine-grained that the platform's ability to scale cpus independently.

In this V2 posting of the proposed dt-binding to support this, I have
included an outline of how this information can be stored and passed onto
relevant OSPM frameworks.

Please see each patch for detailed information.

[v2]
  * Fix errors when running make dt_binding_check
  * Improve commit message description for the dt-binding
  * Add RFC for implementation in cpufreq-core and one of its
    drivers.
