Pull more power management updates from Rafael Wysocki: "These are mostly ARM cpufreq driver updates, including one new MediaTek driver that has just passed all of the reviews, with the addition of a revert of a recent intel_pstate commit, some core cpufreq changes and a DT-related update of the operating performance points (OPP) support code.
Specifics:
- Add new cpufreq driver for the MediaTek MT6779 platform called mediatek-hw along with corresponding DT bindings (Hector.Yuan).
- Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara Gopinath).
- Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu policy flag (Taniya Das).
- Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn Andersson).
- Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV flag (Viresh Kumar).
- Add new cpufreq driver callback to allow drivers to register with the Energy Model in a consistent way and make several drivers use it (Viresh Kumar).
- Change the remaining users of the .ready() cpufreq driver callback to move the code from it elsewhere and drop it from the cpufreq core (Viresh Kumar).
- Revert recent intel_pstate change adding HWP guaranteed performance change notification support to it that led to problems, because the notification in question is triggered prematurely on some systems (Rafael Wysocki).
- Convert the OPP DT bindings to DT schema and clean them up while at it (Rob Herring)"
