Subject: [GIT PULL] More power management updates for v5.16-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.16-rc1-2

with top-most commit dcc0b6f2e63ac3bdcea5c9686de4cb1684f2eb33

 Merge branches 'pm-opp' and 'pm-cpufreq'

on top of commit 833db72142b93a89211c1e43ca0a1e2e16457756

 Merge tag 'pm-5.16-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more power management updates for 5.16-rc1.

These fix 3 intel_pstate driver regressions, fix locking in the core
code suspending and resuming devices during system PM transitions, fix
the handling of cpuidle drivers based on runtime PM during system-wide
suspend, fix 2 issues in the operating performance points (OPP)
framework and resource-managed helpers to it.

Specifics:

 - Fix 2 intel_pstate driver regressions related to the HWP interrupt
   handling added recently (Srinivas Pandruvada).

 - Fix intel_pstate driver regression introduced during the 5.11
   cycle and causing HWP desired performance to be mishandled in
   some cases when switching driver modes and during system
   suspend and shutdown (Rafael Wysocki).

 - Fix system-wide device suspend and resume locking to avoid
   deadlocks when device objects are deleted during a system-wide
   PM transition (Rafael Wysocki).

 - Modify system-wide suspend of devices to prevent cpuidle drivers
   based on runtime PM from misbehaving during the "no IRQ" phase of
   it (Ulf Hansson).

 - Fix return value of _opp_add_static_v2() helper (YueHaibing).

 - Fix required-opp handle count (Pavankumar Kondeti).

 - Add resource managed OPP helpers, update dev_pm_opp_attach_genpd(),
   update their devfreq users, and make minor DT binding change (Dmitry
   Osipenko).

Thanks!
