Linus Torvalds d422555f32 More power management updates for 5.16-rc1
- 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).

Pull more power management updates from Rafael Wysocki:
 "These fix three 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 two issues in the operating
  performance points (OPP) framework and resource-managed helpers to it.

  Specifics:

   - Fix two 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)"

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.
