with top-most commit 7544a367adc1ce5e9cc62315b4c32dc72b509451

 Merge branches 'pm-sleep', 'pm-runtime', 'pm-powercap' and 'pm-tools'

 Linux 7.2-rc6

to receive power management updates for 7.3-rc1.

As it has been the case for quite some time, this set of changes is
dominated by cpufreq updates including intel-pstate and amd-pstate
driver updates, minor fixes and cleanups of other assorted cpufreq
drivers, schedutil governor updates, fixes of the Rust bindings, new
hardware support (IPQ5210 in qcom-nvmem), and some updates of self
tests related to cpufreq.

The second largest group of changes are cpuidle updates consisting of
intel_idle driver updates and ACPI processor idle driver updates, both
mostly related to ACPI _LPI support.

There are also updates related to system sleep, mostly in the
hibernation core code, two operating performance points (OPP) updates,
one runtime PM framework update, one power capping update, and some
tools updates including the addition of ACPI CPPC support to cpupower.

Specifics:

 - Minor fixes and cleanups in assorted cpufreq drivers (Dan Carpenter,
   Guru Das Srinagesh, Haoxiang Li, Karl Mehltretter, Sasha Finkelstein,
   and Pan Chuang)

 - Fix cpufreq table creation and bios_limits() callback in the Rust
   bindings (Priya Bala Govindasamy)

 - Add IPQ5210 support to qcom-nvmem driver (Varadarajan Narayanan)

 - Adjust the .adjust_perf() cpufreq driver callback to allow the
   maximum performance value to be passed to drivers and update the
   intel_pstate driver to use it (Rafael Wysocki)

 - Set policy->cur to the actual requested frequency in the intel_pstate
   driver when the performance policy is used (Rafael Wysocki)

 - Simplify HWP handling on Broadwell processors in intel_pstate (Rafael
   Wysocki)

 - Fix setting minimum P-state at init time in intel_pstate (Rafael
   Wysocki)

 - Consolidate frequency values computation in intel_pstate and clean up
   code in that driver (Rafael Wysocki)

 - Add missing kernel-doc descriptions for structure and union members
   in the amd-pstate driver (David Vernet)

 - Handle missing policy in dynamic EPP callbacks in the amd-pstate
   driver (EDAMAMEX)

 - Introduce EXPORT_SYMBOL_FOR_PSTATE_UT() to export amd-pstate driver
   symbols to the amd-pstate-ut subdriver (K Prateek Nayak)

 - Add dynamic EPP as an "energy_performance_preference" mode in
   amd-pstate, remove the "amd_dynamic_epp" kernel command line option
   and the "dynamic_epp" sysfs attribute, and update the dynamic_epp
   documentation accordingly (K Prateek Nayak)

 - Add unit tests for CPPC Performance Priority and the "dynamic" EPP
   mode in the amd-pstate driver (K Prateek Nayak)

 - Set min_limit_freq based on bios_min_perf in amd-pstate and remove
   the defensive check for bios_min_perf from it (K Prateek Nayak)

 - Fix EPP return type and handle errors in amd-pstate during
   initialization, toggle auto_sel in active mode on shared memory
   systems, and cache the firmware programmed EPP value (Marco Scardovi)

 - Skip tests in amd-pstate-ut if the amd-pstate driver is not in active
   use (Qianheng Peng)

 - Replace sprintf() with sysfs_emit() in sysfs show in the cpufreq
   schedutil governor and fix a self-contradictory comment in
   sugov_iowait_apply() (Zhongqiu Han)

 - Fix the usage example for the sampling_rate tunable of the ondemand
   cpufreq governor in admin-guide (wangxiaodong)

 - Avoid using deep idle states during initialization in the intel_idle
   driver to work around device handling issues (Rafael Wysocki)

 - Fix and refactor the ACPI processor driver code related to ACPI _LPI
   support and add ACPI _LPI support to intel_idle based on that ACPI
   processor driver update (Rafael Wysocki)

 - Backup and restore governor for cpufreq sptests (Yiwei Lin)

 - Remove unnecessary sudo from quick_shuffle() and remove unused local
   variables from switch_show_governor() in cpufreq selftests (Jinseok
   Kim)

 - Rename the PM core module parameter prefix to "pm" and allow the PM
   transition (DPM) watchdog to be disabled by default (Tzung-Bi Shih)

 - Fix off-by-one in wakelocks number limit check in the system sleep
   sysfs interface (Haowen Tu)

 - Remove kernel-doc markings from helper descriptions in the core
   hibernation code (Adi Nata)

 - Use %pe to print error pointer values in the hibernation core (Ronan
   Marchal)

 - Fix memory leak in snapshot_write_next() error path (Malaya Kumar
   Rout)

 - Delay allocating and linking the next swap_map_page in the
   hibernation image saving code until another image page actually
   needs to be recorded (Haesung Kim)

 - Fix cleanup ordering around scope-based pointers in OPP (Gregor
   Herburger).

 - Use clk_get_optional() for optional clocks in OPP (Praveen Talari).

 - Stop setting runtime_error on runtime resume callback failures to
   allow drivers to recover from resume issues (Praveen Talari)

 - Handle PMU registration failure during probe in the intel_rapl_tpmi
   driver (Sumeet Pawnikar)

 - Avoid optional imports in intel_pstate_tracer unless they are really
   needed (Yousef Alhouseen)

 - Add generic CPPC performance display to the cpupower utility, build
   and call CPPC information on non-AMD processors, make cpupower print
   kernel and hardware frequency information, and add libm to cpupower
   for generic CPPC view (Jeremy Linton)

 - Remove conditional return with no effect from cpupower (Sang-Heon
   Jeon)

Thanks!
