Subject: [GIT PULL] More power management updates for v5.14-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.14-rc1-2

with top-most commit 843372db2e3bf9694e98a1ff9d0da6dc3d53aab8

 Merge branches 'pm-cpuidle', 'pm-sleep' and 'pm-domains'

on top of commit 3563f55ce65462063543dfa6a8d8c7fbfb9d7772

 Merge tag 'pm-5.14-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more power management updates for 5.14-rc1.

These include cpufreq core simplifications and fixes, cpufreq
driver updates, cpuidle driver update, a generic power domains
(genpd) locking fix and a debug-related simplification of the PM
core.

Specifics:

 - Drop the ->stop_cpu() (not really useful) and ->resolve_freq()
   (unused) cpufreq driver callbacks and modify the users of the
   former accordingly (Viresh Kumar, Rafael Wysocki).

 - Add frequency invariance support to the ACPI CPPC cpufreq driver
   again along with the related fixes and cleanups (Viresh Kumar).

 - Update the Meditak, qcom and SCMI ARM cpufreq drivers (Fabien
   Parent, Seiya Wang, Sibi Sankar, Christophe JAILLET).

 - Rename black/white-lists in the DT cpufreq driver (Viresh Kumar).

 - Add generic performance domains support to the dvfs DT bindings
   (Sudeep Holla).

 - Refine locking in the generic power domains (genpd) support code
   to avoid lock dependency issues (Stephen Boyd).

 - Update the MSM and qcom ARM cpuidle drivers (Bartosz Dudziak).

 - Simplify the PM core debug code by using ktime_us_delta() to
   compute time interval lengths (Mark-PK Tsai).

Thanks!
