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)"
