Hi Linus,

Please pull from the tag

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

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.


- 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

- 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



Alexandre Belloni (1):
PM: sleep: check RTC features instead of ops in suspend_test

Geert Uytterhoeven (1):
PM: domains: Fix domain attach for CONFIG_PM_OPP=n

PCI: PM: Enable PME if it can be signaled from D3cold

Rajendra Nayak (3):
opp: Don't print an error if required-opps is missing
PM: domains: Add support for 'required-opps' to set default perf state

cpufreq: intel_pstate: Process HWP Guaranteed change notification

Sumeet Pawnikar (1):
powercap: Add Power Limit4 support for Alder Lake SoC

Valentin Schneider (2):
PM: cpu: Make notifier chain use a raw_spinlock_t
notifier: Remove atomic_notifier_call_chain_robust()
