Hi All, In this V3 posting I have replaced the new dt-binding with minor changes/ improvements for opp (since we are now using opp tables instead). The RFC still stands on how to make this info available to sw consumers. In the RFC, I am proposing a simple addition of a performance dependencies cpumask in CPUFreq core and an example of how drivers and consumers would make use of it. I also propose an alternative approach, which does not require changes in CPUFreq core, but - possibly - in all the consumers. This is to support systems where exposed cpu performance controls are more fine-grained that the platform's ability to scale cpus independently. [v3] * Remove proposal for new 'cpu-performance-dependencies' as we instead can reuse the opp table. * Update documentation for devicetree/bindings/opp * Minor changes within opp to support empty opp table * Rework the RFC by adding a second proposal [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.
