Merge tag 'pm-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "These are mostly minor improvements all over including new CPU IDs for
  the Intel RAPL driver, an Energy Model rework to use micro-Watt as the
  power unit, cpufreq fixes and cleanus, cpuidle updates, devfreq
  updates, documentation cleanups and a new version of the pm-graph
  suite of utilities.

  Specifics:

   - Make cpufreq_show_cpus() more straightforward (Viresh Kumar).

   - Drop unnecessary CPU hotplug locking from store() used by cpufreq
     sysfs attributes (Viresh Kumar).

   - Make the ACPI cpufreq driver support the boost control interface on
     Zhaoxin/Centaur processors (Tony W Wang-oc).

   - Print a warning message on attempts to free an active cpufreq
     policy which should never happen (Viresh Kumar).

   - Fix grammar in the Kconfig help text for the loongson2 cpufreq
     driver (Randy Dunlap).

   - Use cpumask_var_t for an on-stack CPU mask in the ondemand cpufreq
     governor (Zhao Liu).

   - Add trace points for guest_halt_poll_ns grow/shrink to the haltpoll
     cpuidle driver (Eiichi Tsukata).

   - Modify intel_idle to treat C1 and C1E as independent idle states on
     Sapphire Rapids (Artem Bityutskiy).

   - Extend support for wakeirq to callback wrappers used during system
     suspend and resume (Ulf Hansson).

   - Defer waiting for device probe before loading a hibernation image
     till the first actual device access to avoid possible deadlocks
     reported by syzbot (Tetsuo Handa).

   - Unify device_init_wakeup() for PM_SLEEP and !PM_SLEEP (Bjorn
     Helgaas).

   - Add Raptor Lake-P to the list of processors supported by the Intel
     RAPL driver (George D Sworo).

   - Add Alder Lake-N and Raptor Lake-P to the list of processors for
     which Power Limit4 is supported in the Intel RAPL driver (Sumeet
     Pawnikar).

   - Make pm_genpd_remove() check genpd_debugfs_dir against NULL before
     attempting to remove it (Hsin-Yi Wang).

   - Change the Energy Model code to represent power in micro-Watts and
     adjust its users accordingly (Lukasz Luba).

   - Add new devfreq driver for Mediatek CCI (Cache Coherent
     Interconnect) (Johnson Wang).

   - Convert the Samsung Exynos SoC Bus bindings to DT schema of
     exynos-bus.c (Krzysztof Kozlowski).

   - Address kernel-doc warnings by adding the description for unused
     function parameters in devfreq core (Mauro Carvalho Chehab).

   - Use NULL to pass a null pointer rather than zero according to the
     function propotype in imx-bus.c (Colin Ian King).

   - Print error message instead of error interger value in
     tegra30-devfreq.c (Dmitry Osipenko).

   - Add checks to prevent setting negative frequency QoS limits for
     CPUs (Shivnandan Kumar).

   - Update the pm-graph suite of utilities to the latest revision 5.9
     including multiple improvements (Todd Brandt).

   - Drop pme_interrupt reference from the PCI power management
     documentation (Mario Limonciello)"
