Subject: [GIT PULL] Power management updates for v5.15-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.15-rc1

with top-most commit fe583359ddf0d509275b87b635fa8b2e3794321e

 Merge branches 'pm-pci', 'pm-sleep', 'pm-domains' and 'powercap'

on top of commit 7ee5fd12e8cac91bdec6de8417b030ed05d5d7ee

 Merge branch 'pm-opp'

to receive power management updates for 5.15-rc1.

These address some PCI device power management issues, add new
hardware support to the RAPL power capping driver, add HWP guaranteed
performance change notification support to the intel_pstate driver,
replace deprecated CPU-hotplug functions in a few places, update CPU
PM notifiers to use raw spinlocks, update the PM domains framework
(new DT property support, Kconfig fix), do a couple of cleanups in
code related to system sleep, and improve the energy model and
the schedutil cpufreq governor.

Specifics:

 - Address 3 PCI device power management issues (Rafael Wysocki).

 - Add Power Limit4 support for Alder Lake to the Intel RAPL power
   capping driver (Sumeet Pawnikar).

 - Add HWP guaranteed performance change notification support to
   the intel_pstate driver (Srinivas Pandruvada).

 - Replace deprecated CPU-hotplug functions in code related to power
   management (Sebastian Andrzej Siewior).

 - Update CPU PM notifiers to use raw spinlocks (Valentin Schneider).

 - Add support for 'required-opps' DT property to the generic power
   domains (genpd) framework and use this property for I2C on ARM64
   sc7180 (Rajendra Nayak).

 - Fix Kconfig issue related to genpd (Geert Uytterhoeven).

 - Increase energy calculation precision in the Energy Model (Lukasz
   Luba).

 - Fix kobject deletion in the exit code of the schedutil cpufreq
   governor (Kevin Hao).

 - Unmark some functions as kernel-doc in the PM core to avoid
   false-positive documentation build warnings (Randy Dunlap).

 - Check RTC features instead of ops in suspend_test Alexandre
   Belloni).

Thanks!
