Pull power management updates from Rafael Wysocki:
 "This time, the most visible part are the ACPI CPPC updates from
  Christian Loehle, including CPPC cpufreq driver changes, even though
  updates of cpufreq drivers proper are still the largest topic group.
  However, the updates of cpufreq drivers depend on the ACPI CPPC
  updates, so they should really be counted together and that is well
  over 1/2 of the total commit count.

  Interestingly enough, almost all of the updates included here are
  fixes or cleanups, with some new feature support in the amd-pstate
  cpufreq driver and IPQ9650 support in the qcom-nvmem cpufreq driver.
  The runtime PM documentation improvements from Brian Norris can also
  be mostly regarded as fixes, but a new kunit test goes along with
  them.

  Specifics:

   - Fix multiple issues related to input validation, synchronization,
     access safety, memory layout and register field validation, and
     error handling in the ACPI CPPC library (Christian Loehle and Sumit
     Gupta)

   - Select the frequency-invariance callback per CPU in the CPPC
     cpufreq driver and create the FIE worker before enabling PCC
     callbacks in it to avoid queueing work through a missing worker and
     dereferencing a NULL pointer (Christian Loehle)

   - Update the CPPC cpufreq driver entry in MAINTAINERS and add a new
     entry for the ACPI CPPC library (Christian Loehle)

   - Minor fixes in various cpufreq drivers (Alexander Koskovich, Daniel
     Schwierzeck, Frank Zhang, Haotian Zhang, Kathiravan Thirumoorthy,
     Sumeet Pawnikar, and Xueqin Luo)

   - Fix wrong behaviors on multi-node servers in the Loongson cpufreq
     driver (Huacai Chen)

   - Reject NULL from cpufreq_cpu_get() in the Rust code (Mehmet
     Koseoglu)

   - Add suspend OPP to mediatek cpufreq driver and DT (Ryan Brue)

   - Fixups for a few bugs identified by Sashiko in the amd-pstate
     cpufreq driver (Mario Limoncielloi, Wentao Guan)

   - Initial support for maximum frequency capacity handling on Zen6
     client in amd-pstate (Mario Limonciello)

   - Fix for amd-pstate-ut with 'Requested CPU Min frequency' BIOS
     option (K Prateek Nayak)

   - New Zen6 tuning values for EPP in amd-pstate (Mario Limonciello,
     Vishal Badole)

   - amd-pstate documentation fix (Karl Mehltretter)

   - Restrict deferred downscaling to low load for shared policies in
     the conservative cpufreq governor to avoid undesirable CPU
     frequency reduction in some cases (Shengming Hu)

   - Serialize sugov_start() against rate limit updates in the schedutil
     cpufreq governor to avoid using a stale rate limit value (Hui Su)

   - Prevent cpuidle governors menu and teo from returning idle state 0
     after it has been disabled (Xueqin Luo)

   - Replace min_t() with the better alternatives in the intel_idle
     driver and make it use 2-argument strscpy() (Andy Shevchenko)

   - Fix two repeated phrase instances in cpuidle (Hemanth Selam,
     Syazwina Fazrul)

   - Add rugged Panther Lake support to the intel_rapl power capping
     driver and make it use %pe for printing error pointers (Srinivas
     Pandruvada and Sumeet Pawnikar)

   - Update and improve runtime PM documentation and add a kunit test
     for supplier idle/suspend (Brian Norris)

   - Add a pm_runtime_dont_use_autosuspend() call to pm_runtime_reinit()
     to ensure autosuspend disabling on driver teardown (Joshua Crofts)

   - Ignore page-zero RAM in E820 checksum during hibernation on x86 to
     avoid rejecting images created after kexec() (Matthias Goergens)

   - Add resume event mapping for PMSG_POWEROFF to the PM core to allow
     it to carry out device shutdown in the future (Mario Limonciello)

   - Add DPM watchdog to prepare/late/early/noirq/complete phases of
     device suspend and resume (Mayank Rungta)

   - Update swsusp.txt references to swsusp.rst in hibernation
     documentation (Li Jun)

   - Fix use-after-free of perf domain in netlink doit handlers for
     energy models (Fan Wu)

   - Add synchronize_rcu() back to cpu_pm_unregister_notifier() after it
     was removed inadvertently in previous development cycles to avoid
     use-after-free (Bradley Morgan)

   - Unregister CPU PM notifier outside the timer lock in the
     timer-ti-dm clocksource driver (Bradley Morgan)

   - Fix typo "sucessfully" in a comment in pm_clk_add_clk() kerneldoc
     comment and typo "hierachy" in a comment in pm-graph (Hemanth
     Selam)

   - Fix the return value in dev_pm_opp_get_of_node() kernel-doc (Karl
     Mehltretter)"
