Pull power management updates from Rafael Wysocki: "These add hybrid processors support to the intel_pstate driver and make it work with more processor models when HWP is disabled, make the intel_idle driver use special C6 idle state paremeters when package C-states are disabled, add cooling support to the tegra30 devfreq driver, rework the TEO (timer events oriented) cpuidle governor, extend the OPP (operating performance points) framework to use the required-opps DT property in more cases, fix some issues and clean up a number of assorted pieces of code. Specifics: - Make intel_pstate support hybrid processors using abstract performance units in the HWP interface (Rafael Wysocki). - Add Icelake servers and Cometlake support in no-HWP mode to intel_pstate (Giovanni Gherdovich). - Make cpufreq_online() error path be consistent with the CPU device removal path in cpufreq (Rafael Wysocki). - Clean up 3 cpufreq drivers and the statistics code (Hailong Liu, Randy Dunlap, Shaokun Zhang). - Make intel_idle use special idle state parameters for C6 when package C-states are disabled (Chen Yu). - Rework the TEO (timer events oriented) cpuidle governor to address some theoretical shortcomings in it (Rafael Wysocki). - Drop unneeded semicolon from the TEO governor (Wan Jiabing). - Modify the runtime PM framework to accept unassigned suspend and resume callback pointers (Ulf Hansson). - Improve pm_runtime_get_sync() documentation (Krzysztof Kozlowski). - Improve device performance states support in the generic power domains (genpd) framework (Ulf Hansson). - Fix some documentation issues in genpd (Yang Yingliang). - Make the operating performance points (OPP) framework use the required-opps DT property in use cases that are not related to genpd (Hsin-Yi Wang). - Make lazy_link_required_opp_table() use list_del_init instead of list_del/INIT_LIST_HEAD (Yang Yingliang). - Simplify wake IRQs handling in the core system-wide sleep support code and clean up some coding style inconsistencies in it (Tian Tao, Zhen Lei). - Add cooling support to the tegra30 devfreq driver and improve its DT bindings (Dmitry Osipenko). - Fix some assorted issues in the devfreq core and drivers (Chanwoo Choi, Dong Aisheng, YueHaibing)" * tag 'pm-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (39 commits) PM / devfreq: passive: Fix get_target_freq when not using required-opp cpufreq: Make cpufreq_online() call driver->offline() on errors opp: Allow required-opps to be used for non genpd use cases cpuidle: teo: remove unneeded semicolon in teo_select() dt-bindings: devfreq: tegra30-actmon: Add cooling-cells dt-bindings: devfreq: tegra30-actmon: Convert to schema PM / devfreq: userspace: Use DEVICE_ATTR_RW macro PM: runtime: Clarify documentation when callbacks are unassigned PM: runtime: Allow unassigned ->runtime_suspend|resume callbacks PM: runtime: Improve path in rpm_idle() when no callback PM: hibernate: remove leading spaces before tabs PM: sleep: remove trailing spaces and tabs PM: domains: Drop/restore performance state votes for devices at runtime PM PM: domains: Return early if perf state is already set for the device PM: domains: Split code in dev_pm_genpd_set_performance_state() cpuidle: teo: Use kerneldoc documentation in admin-guide cpuidle: teo: Rework most recent idle duration values treatment cpuidle: teo: Change the main idle state selection logic cpuidle: teo: Cosmetic modification of teo_select() cpuidle: teo: Cosmetic modifications of teo_update() ...
