Merge tag 'pm-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.

There is also some new hardware support (Ice Lake server idle states
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
devfreq), including the elimination of W=1 build warnings from cpufreq
done by Lee Jones.

Specifics:

- Make the Energy Model cover non-CPU devices (Lukasz Luba).

- Add Ice Lake server idle states table to the intel_idle driver and
eliminate a redundant static variable from it (Chen Yu, Rafael
Wysocki).

- Eliminate all W=1 build warnings from cpufreq (Lee Jones).

- Add support for Sapphire Rapids and for Power Limit 4 to the Intel
RAPL power capping driver (Sumeet Pawnikar, Zhang Rui).

- Fix function name in kerneldoc comments in the idle_inject power
capping driver (Yangtao Li).

- Fix locking issues with cpufreq governors and drop a redundant
"weak" function definition from cpufreq (Viresh Kumar).

- Rearrange cpufreq to register non-modular governors at the
core_initcall level and allow the default cpufreq governor to be
specified in the kernel command line (Quentin Perret).

- Extend, fix and clean up the intel_pstate driver (Srinivas
Pandruvada, Rafael Wysocki):

* Add a new sysfs attribute for disabling/enabling CPU
energy-efficiency optimizations in the processor.

* Make the driver avoid enabling HWP if EPP is not supported.

* Allow the driver to handle numeric EPP values in the sysfs
interface and fix the setting of EPP via sysfs in the active
mode.

* Eliminate a static checker warning and clean up a kerneldoc
comment.

- Clean up some variable declarations in the powernv cpufreq driver
(Wei Yongjun).

- Fix up the ->enter_s2idle callback definition to cover the case
when it points to the same function as ->idle correctly (Neal Liu).

- Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson).

- Make the PM core emit "changed" uevent when adding/removing the
"wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi).

- Add a helper macro for declaring PM callbacks and use it in the MMC
jz4740 driver (Paul Cercueil).

- Fix white space in some places in the hibernate code and make the
system-wide PM code use "const char *" where appropriate (Xiang
Chen, Alexey Dobriyan).

- Add one more "unsafe" helper macro to the freezer to cover the NFS
use case (He Zhe).

- Change the language in the generic PM domains framework to use
parent/child terminology and clean up a typo and some comment
fromatting in that code (Kees Cook, Geert Uytterhoeven).

- Update the operating performance points OPP framework (Lukasz Luba,
Andrew-sh.Cheng, Valdis Kletnieks):

* Refactor dev_pm_opp_of_register_em() and update related drivers.

* Add a missing function export.

* Allow disabled OPPs in dev_pm_opp_get_freq().

- Update devfreq core and drivers (Chanwoo Choi, Lukasz Luba, Enric
Balletbo i Serra, Dmitry Osipenko, Kieran Bingham, Marc Zyngier):

* Add support for delayed timers to the devfreq core and make the
Samsung exynos5422-dmc driver use it.

* Unify sysfs interface to use "df-" as a prefix in instance
names consistently.

* Fix devfreq_summary debugfs node indentation.

* Add the rockchip,pmu phandle to the rk3399_dmc driver DT
bindings.

* List Dmitry Osipenko as the Tegra devfreq driver maintainer.

* Fix typos in the core devfreq code.

- Update the pm-graph utility to version 5.7 including a number of
fixes related to suspend-to-idle (Todd Brandt).

- Fix coccicheck errors and warnings in the cpupower utility (Shuah
Khan).

- Replace HTTP links with HTTPs ones in multiple places (Alexander A.
Klimov)"
