Merge tag 'pm-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These include two new drivers (cpufreq driver for Apple SoC CPU P-states and the SCMI Powercap based power capping driver), other new hardware support and driver extensions (Qualcomm cpufreq driver and its DT bindings, TI cpufreq driver, intel_pstate, intel-uncore-freq), a bunch of fixes and cleanups all over and a cpupower utility update including new features related to RAPL support. Specifics: - Fix nasty and hard to debug race condition introduced by mistake in the runtime PM core code and clean up that code somewhat on top of the fix (Rafael Wysocki) - Generalize of_perf_domain_get_sharing_cpumask phandle format (Hector Martin) - Add new cpufreq driver for Apple SoC CPU P-states (Hector Martin) - Update Qualcomm cpufreq driver (Manivannan Sadhasivam, Chen Hui): - CPU clock provider support - Generic cleanups or reorganization - Potential memleak fix - Fix of the return value of cpufreq_driver->get() - Update Qualcomm cpufreq driver's DT bindings (Manivannan Sadhasivam, Rob Herring, Melody Olvera): - Support for CPU clock provider - Missing cache-related properties fixes - Support for QDU1000/QRU1000 - Add support for ti,am625 SoC and enable build of ti-cpufreq for ARCH_K3 (Dave Gerlach, and Vibhore Vardhan) - Use flexible array to simplify memory allocation in the tegra186 cpufreq driver (Christophe JAILLET) - Convert cpufreq statistics code to use sysfs_emit_at() (ye xingchen) - Allow intel_pstate to use no-HWP mode on Sapphire Rapids (Giovanni Gherdovich) - Add missing pci_dev_put() to the amd_freq_sensitivity cpufreq driver (Xiongfeng Wang) - Initialize the kobj_unregister completion before calling kobject_init_and_add() in the cpufreq core code (Yongqiang Liu) - Defer setting boost MSRs in the ACPI cpufreq driver (Stuart Hayes, Nathan Chancellor) - Make intel_pstate accept initial EPP value of 0x80 (Srinivas Pandruvada) - Make read-only array sys_clk_src in the SPEAr cpufreq driver static (Colin Ian King) - Make array speeds in the longhaul cpufreq driver static (Colin Ian King) - Use str_enabled_disabled() helper in the ACPI cpufreq driver (Andy Shevchenko) - Drop a reference to CVS from cpufreq documentation (Conghui Wang) - Improve kernel messages printed by the PSCI cpuidle driver (Ulf Hansson) - Make the DT cpuidle driver return the correct number of parsed idle states, clean it up and clarify a comment in it (Ulf Hansson) - Modify the tasks freezing code to avoid using pr_cont() and refine an error message printed by it (Rafael Wysocki) - Make the hibernation core code complain about memory map mismatches during resume to help diagnostics (Xueqin Luo) - Fix mistake in a kerneldoc comment in the hibernation code (xiongxin) - Reverse the order of performance and enabling operations in the generic power domains code (Abel Vesa) - Power off[on] domains in hibernate .freeze[thaw]_noirq hook of in the generic power domains code (Abel Vesa) - Consolidate genpd_restore_noirq() and genpd_resume_noirq() (Shawn Guo) - Pass generic PM noirq hooks to genpd_finish_suspend() (Shawn Guo) - Drop generic power domain status manipulation during hibernate restore (Shawn Guo) - Fix compiler warnings with make W=1 in the idle_inject power capping driver (Srinivas Pandruvada) - Use kstrtobool() instead of strtobool() in the power capping sysfs interface (Christophe JAILLET) - Add SCMI Powercap based power capping driver (Cristian Marussi) - Add Emerald Rapids support to the intel-uncore-freq driver (Artem Bityutskiy) - Repair slips in kernel-doc comments in the generic notifier code (Lukas Bulwahn) - Fix several DT issues in the OPP library reorganize code around opp-microvolt-<named> DT property (Viresh Kumar) - Allow any of opp-microvolt, opp-microamp, or opp-microwatt properties to be present without the others present (James Calligeros) - Fix clock-latency-ns property in DT example (Serge Semin) - Add a private governor_data for devfreq governors (Kant Fan) - Reorganize devfreq code to use device_match_of_node() and devm_platform_get_and_ioremap_resource() instead of open coding them (ye xingchen, Minghao Chi) - Make cpupower choose base_cpu to display default cpupower details instead of picking CPU 0 (Saket Kumar Bhaskar) - Add Georgian translation to cpupower documentation (Zurab Kargareteli) - Introduce powercap intel-rapl library, powercap-info command, and RAPL monitor into cpupower (Thomas Renninger)" * tag 'pm-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (64 commits) PM: runtime: Adjust white space in the core code cpufreq: Remove CVS version control contents from documentation cpufreq: stats: Convert to use sysfs_emit_at() API cpufreq: ACPI: Only set boost MSRs on supported CPUs PM: sleep: Refine error message in try_to_freeze_tasks() PM: sleep: Avoid using pr_cont() in the tasks freezing code PM: runtime: Relocate rpm_callback() right after __rpm_callback() PM: runtime: Do not call __rpm_callback() from rpm_idle() PM / devfreq: event: use devm_platform_get_and_ioremap_resource() PM / devfreq: event: Use device_match_of_node() PM / devfreq: Use device_match_of_node() powercap: idle_inject: Fix warnings with make W=1 PM: hibernate: Complain about memory map mismatches during resume dt-bindings: cpufreq: cpufreq-qcom-hw: Add QDU1000/QRU1000 cpufreq cpufreq: tegra186: Use flexible array to simplify memory allocation cpupower: rapl monitor -
