Merge tag 'pm-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
"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).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
