Pull power management updates from Rafael Wysocki:
 "By the number of commits, cpufreq is the leading party (again) and the
  most visible change there is the removal of the omap-cpufreq driver
  that has not been used for a long time (good riddance). There are also
  quite a few changes in the cppc_cpufreq driver, mostly related to
  fixing its frequency invariance engine in the case when the CPPC
  registers used by it are not in PCC. In addition to that, support for
  AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev
  list is updated for some platforms. The remaining cpufreq changes are
  assorted fixes and cleanups.

  Next up is cpuidle and the changes there are dominated by intel_idle
  driver updates, mostly related to the new command line facility
  allowing users to adjust the list of C-states used by the driver.
  There are also a few updates of cpuidle governors, including two menu
  governor fixes and some refinements of the teo governor, and a
  MAINTAINERS update adding Christian Loehle as a cpuidle reviewer.
  [Thanks for stepping up Christian!]

  The most significant update related to system suspend and hibernation
  is the one to stop freezing the PM runtime workqueue during system PM
  transitions which allows some deadlocks to be avoided. There is also a
  fix for possible concurrent bit field updates in the core device
  suspend code and a few other minor fixes.

  Apart from the above, several drivers are updated to discard the
  return value of pm_runtime_put() which is going to be converted to a
  void function as soon as everybody stops using its return value, PL4
  support for Ice Lake is added to the Intel RAPL power capping driver,
  and there are assorted cleanups, documentation fixes, and some
  cpupower utility improvements.

  Specifics:

   - Remove the unused omap-cpufreq driver (Andreas Kemnade)

   - Optimize error handling code in cpufreq_boost_trigger_state() and
     make cpufreq_boost_trigger_state() return -EOPNOTSUPP if no policy
     supports boost (Lifeng Zheng)

   - Update cpufreq-dt-platdev list for tegra, qcom, TI (Aaron Kling,
     Dhruva Gole, and Konrad Dybcio)

   - Minor improvements to the cpufreq and cpumask rust implementation
     (Alexandre Courbot, Alice Ryhl, Tamir Duberstein, and Yilin Chen)

   - Add support for AM62L3 SoC to the ti-cpufreq driver (Dhruva Gole)

   - Update arch_freq_scale in the CPPC cpufreq driver's frequency
     invariance engine (FIE) in scheduler ticks if the related CPPC
     registers are not in PCC (Jie Zhan)

   - Assorted minor cleanups and improvements in ARM cpufreq drivers
     (Juan Martinez, Felix Gu, Luca Weiss, and Sergey Shtylyov)

   - Add generic helpers for sysfs show/store to cppc_cpufreq (Sumit
     Gupta)

   - Make the scaling_setspeed cpufreq sysfs attribute return the actual
     requested frequency to avoid confusion (Pengjie Zhang)

   - Simplify the idle CPU time granularity test in the ondemand cpufreq
     governor (Frederic Weisbecker)

   - Enable asym capacity in intel_pstate only when CPU SMT is not
     possible (Yaxiong Tian)

   - Update the description of rate_limit_us default value in cpufreq
     documentation (Yaxiong Tian)

   - Add a command line option to adjust the C-states table in the
     intel_idle driver, remove the 'preferred_cstates' module parameter
     from it, add C-states validation to it and clean it up (Artem
     Bityutskiy)

   - Make the menu cpuidle governor always check the time till the
     closest timer event when the scheduler tick has been stopped to
     prevent it from mistakenly selecting the deepest available idle
     state (Rafael Wysocki)

   - Update the teo cpuidle governor to avoid making suboptimal
     decisions in certain corner cases and generally improve idle state
     selection accuracy (Rafael Wysocki)

   - Remove an unlikely() annotation on the early-return condition in
     menu_select() that leads to branch misprediction 100% of the time
     on systems with only 1 idle state enabled, like ARM64 servers
     (Breno Leitao)

   - Add Christian Loehle to MAINTAINERS as a cpuidle reviewer
     (Christian Loehle)

   - Stop flagging the PM runtime workqueue as freezable to avoid system
     suspend and resume deadlocks in subsystems that assume asynchronous
     runtime PM to work during system-wide PM transitions (Rafael
     Wysocki)

   - Drop redundant NULL pointer checks before acomp_request_free() from
     the hibernation code handling image saving (Rafael Wysocki)

   - Update wakeup_sources_walk_start() to handle empty lists of wakeup
     sources as appropriate (Samuel Wu)

   - Make dev_pm_clear_wake_irq() check the power.wakeirq value under
     power.lock to avoid race conditions (Gui-Dong Han)

   - Avoid bit field races related to power.work_in_progress in the core
     device suspend code (Xuewen Yan)

   - Make several drivers discard pm_runtime_put() return value in
     preparation for converting that function to a void one (Rafael
     Wysocki)

   - Add PL4 support for Ice Lake to the Intel RAPL power capping driver
     (Daniel Tang)

   - Replace sprintf() with sysfs_emit() in power capping sysfs show
     functions (Sumeet Pawnikar)

   - Make dev_pm_opp_get_level() return value match the documentation
     after a previous update of the latter (Aleks Todorov)

   - Use scoped for each OF child loop in the OPP code (Krzysztof
     Kozlowski)

   - Fix a bug in an example code snippet and correct typos in the
     energy model management documentation (Patrick Little)

   - Fix miscellaneous problems in cpupower (Kaushlendra Kumar):
      * idle_monitor: Fix incorrect value logged after stop
      * Fix inverted APERF capability check
      * Use strcspn() to strip trailing newline
      * Reset errno before strtoull()
      * Show C0 in idle-info dump

   - Improve cpupower installation procedure by making the systemd step
     optional and allowing users to disable the installation of
     systemd's unit file (João Marcos Costa)"
