Hi, This patchset adds support to build a single-coefficient dynamic power model for a CPU. The model is used by the CPU cooling device to provide an estimate of power consumption and also translate allocated power to performance cap. Patch 1 extends the CPU nodes binding to provide an optional dynamic power coefficient which can be used to create a dynamic power model for the CPUs. This model is used to constrain device power consumption (using power_allocator governor) when the system is thermally constrained. Patches 2-3 extends the cpufreq-dt and arm_big_little driver to register cpu cooling devices with the dynamic coefficient when provided. The patches were previously posted as part of [0][1]. Since the last posting Mediatek platform 8173 is also building on these bindings to build the power model. Feedback on the bindings would be particularly appreciated.
