Merge tag 'pm-5.20-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki: "These are ARM cpufreq updates and operating performance points (OPP) updates plus one cpuidle update adding a new trace point. Specifics: - Fix return error code in mtk_cpu_dvfs_info_init (Yang Yingliang). - Minor cleanups and support for new boards for Qcom cpufreq drivers (Bryan O'Donoghue, Konrad Dybcio, Pierre Gondois, and Yicong Yang). - Fix sparse warnings for Tegra cpufreq driver (Viresh Kumar). - Make dev_pm_opp_set_regulators() accept NULL terminated list (Viresh Kumar). - Add dev_pm_opp_set_config() and friends and migrate other users and helpers to using them (Viresh Kumar). - Add support for multiple clocks for a device (Viresh Kumar and Krzysztof Kozlowski). - Configure resources before adding OPP table for Venus (Stanimir Varbanov). - Keep reference count up for opp->np and opp_table->np while they are still in use (Liang He). - Minor OPP cleanups (Viresh Kumar and Yang Li). - Add a trace event for cpuidle to track missed (too deep or too shallow) wakeups (Kajetan Puchalski)" * tag 'pm-5.20-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (55 commits) cpuidle: Add cpu_idle_miss trace event venus: pm_helpers: Fix warning in OPP during probe OPP: Don't drop opp->np reference while it is still in use OPP: Don't drop opp_table->np reference while it is still in use cpufreq: tegra194: Staticize struct tegra_cpufreq_soc instances dt-bindings: cpufreq: cpufreq-qcom-hw: Add SM6375 compatible dt-bindings: opp: Add msm8939 to the compatible list dt-bindings: opp: Add missing compat devices dt-bindings: opp: opp-v2-kryo-cpu: Fix example binding checks cpufreq: Change order of online() CB and policy->cpus modification cpufreq: qcom-hw: Remove deprecated irq_set_affinity_hint() call cpufreq: qcom-hw: Disable LMH irq when disabling policy cpufreq: qcom-hw: Reset cancel_throttle when policy is re-enabled cpufreq: qcom-cpufreq-hw: use HZ_PER_KHZ macro in units.h cpufreq: mediatek: fix error return code in mtk_cpu_dvfs_info_init() OPP: Remove dev{m}_pm_opp_of_add_table_noclk() PM / devfreq: tegra30: Register config_clks helper OPP: Allow config_clks helper for single clk case OPP: Provide a simple implementation to configure multiple clocks OPP: Assert clk_count == 1 for single clk helpers ...
