30f3490978 More power management updates for 5.15-rc1
- Add new cpufreq driver for the MediaTek MT6779 platform called
    mediatek-hw along with corresponding DT bindings (Hector.Yuan).
 
  - Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
    Gopinath).
 
  - Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
    policy flag (Taniya Das).
 
  - Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
    Andersson).
 
  - Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
    flag (Viresh Kumar).
 
  - Add new cpufreq driver callback to allow drivers to register
    with the Energy Model in a consistent way and make several
    drivers use it (Viresh Kumar).
 
  - Change the remaining users of the .ready() cpufreq driver callback
    to move the code from it elsewhere and drop it from the cpufreq
    core (Viresh Kumar).
 
  - Revert recent intel_pstate change adding HWP guaranteed performance
    change notification support to it that led to problems, because
    the notification in question is triggered prematurely on some
    systems (Rafael Wysocki).
 
  - Convert the OPP DT bindings to DT schema and clean them up while
    at it (Rob Herring).

Merge tag 'pm-5.15-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These are mostly ARM cpufreq driver updates, including one new
  MediaTek driver that has just passed all of the reviews, with the
  addition of a revert of a recent intel_pstate commit, some core
  cpufreq changes and a DT-related update of the operating performance
  points (OPP) support code.

  Specifics:

   - Add new cpufreq driver for the MediaTek MT6779 platform called
     mediatek-hw along with corresponding DT bindings (Hector.Yuan).

   - Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
     Gopinath).

   - Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
     policy flag (Taniya Das).

   - Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
     Andersson).

   - Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
     flag (Viresh Kumar).

   - Add new cpufreq driver callback to allow drivers to register with
     the Energy Model in a consistent way and make several drivers use
     it (Viresh Kumar).

   - Change the remaining users of the .ready() cpufreq driver callback
     to move the code from it elsewhere and drop it from the cpufreq
     core (Viresh Kumar).

   - Revert recent intel_pstate change adding HWP guaranteed performance
     change notification support to it that led to problems, because the
     notification in question is triggered prematurely on some systems
     (Rafael Wysocki).

b3beca7618 cpufreq: Remove ->resolve_freq()
Commit e3c062360870 ("cpufreq: add cpufreq_driver_resolve_freq()")
introduced this callback, back in 2016, for drivers that provide the
->target() callback.

The kernel hasn't seen a single user of it in the past 5 years and
it is not likely to be used any time soon.

Remove it for now.
