Subject[GIT PULL] Power management updates for v5.10-rc1
Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.10-rc1

with top-most commit 16641d81f9ff5f902d084754c84b2bde3a60bc6e

Merge branches 'pm-avs' and 'powercap'

on top of commit 549738f15da0e5a00275977623be199fbbf7df50

Linux 5.9-rc8

to receive power management updates for 5.10-rc1.

These rework the collection of cpufreq statistics to allow it to take
place if fast frequency switching is enabled in the governor, rework
the frequency invariance handling in the cpufreq core and drivers,
add new hardware support to a couple of cpufreq drivers, fix a number
of assorted issues and clean up the code all over.

Specifics:

- Rework cpufreq statistics collection to allow it to take place
when fast frequency switching is enabled in the governor (Viresh
Kumar).

- Make the cpufreq core set the frequency scale on behalf of the
driver and update several cpufreq drivers accordingly (Ionela
Voinescu, Valentin Schneider).

- Add new hardware support to the STI and qcom cpufreq drivers and
improve them (Alain Volmat, Manivannan Sadhasivam).

- Fix multiple assorted issues in cpufreq drivers (Jon Hunter,
Krzysztof Kozlowski, Matthias Kaehlcke, Pali Rohár, Stephan
Gerhold, Viresh Kumar).

- Fix several assorted issues in the operating performance points
(OPP) framework (Stephan Gerhold, Viresh Kumar).

- Allow devfreq drivers to fetch devfreq instances by DT enumeration
instead of using explicit phandles and modify the devfreq core
code to support driver-specific devfreq DT bindings (Leonard
Crestez, Chanwoo Choi).

- Improve initial hardware resetting in the tegra30 devfreq driver
and clean up the tegra cpuidle driver (Dmitry Osipenko).

- Update the cpuidle core to collect state entry rejection
statistics and expose them via sysfs (Lina Iyer).

- Improve the ACPI _CST code handling diagnostics (Chen Yu).

- Update the PSCI cpuidle driver to allow the PM domain
initialization to occur in the OSI mode as well as in the PC
mode (Ulf Hansson).

- Rework the generic power domains (genpd) core code to allow
domain power off transition to be aborted in the absence of the
"power off" domain callback (Ulf Hansson).

- Fix two suspend-to-idle issues in the ACPI EC driver (Rafael
Wysocki).

- Fix the handling of timer_expires in the PM-runtime framework on
32-bit systems and the handling of device links in it (Grygorii
Strashko, Xiang Chen).

- Add IO requests batching support to the hibernate image saving and
reading code and drop a bogus get_gendisk() from there (Xiaoyi
Chen, Christoph Hellwig).

- Allow PCIe ports to be put into the D3cold power state if they
are power-manageable via ACPI (Lukas Wunner).

- Add missing header file include to a power capping driver (Pujin
Shi).

- Clean up the qcom-cpr AVS driver a bit (Liu Shixin).

- Kevin Hilman steps down as designated reviewer of adaptive voltage
scaling (AVS) drivers (Kevin Hilman).

Note that because of the Kevin Hilman's resignation (so long, and
thanks for all the fish Kevin!), the maintenance of AVS drivers is
expected to be transferred to arm-soc.

Thanks!
