Pull power management updates from Rafael Wysocki:
"These are mostly cpufreq updates, including a significant intel-pstate
driver update and several amd-pstate improvements plus some updates of
ARM cpufreq drivers, general fixes and cleanups.

Also included are changes related to system sleep, power capping
updates adding support for a new platform and a new hardware feature
(among other things), a Samsung exynos-asv driver update allowing it
to change its Energy Model after adjusting voltage, minor cpuidle and
devfreq updates and a small documentation cleanup.

Specifics:

and make it update the maximum CPU frequency consistently
regardless of the reason on top of a number of cleanups (Rafael
Wysocki)

- Add missing checks for NULL .exit() cpufreq driver callback to the
cpufreq core (Viresh Kumar)

- Prevent pulicy->max from going above the frequency QoS maximum
value when cpufreq_frequency_table_verify() is used (Xuewen Yan)

- Prevent a negative CPU number or frequency value from being printed
if they are really large (Joshua Yeong)

requested by TR40 processor users who expect improved performance
and lower system temperature (Perry Yuan)

- Change latency and delay values to be read from platform firmware
firstly for more accurate timing (Perry Yuan)

- A new quirk is introduced for supporting amd-pstate on legacy
processors which either lack CPPC capability, or only only have
CPPC v2 capability (Perry Yuan)

- Sun50i cpufreq: Add support for opp_supported_hw, H616 platform and
general cleanups (Andre Przywara, Martin Botka, Brandon Cheo Fusi,
Dan Carpenter, Viresh Kumar)

- CPPC cpufreq: Fix possible null pointer dereference (Aleksandr
Mishin)

- Eliminate uses of of_node_put() from cpufreq (Javier Carrasco,
Shivani Gupta)

Merge tag 'pm-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.

There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate
and more.

Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system
suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

Specifics:

- Allow the Energy Model to be updated dynamically (Lukasz Luba)

- Add support for LZ4 compression algorithm to the hibernation image
creation and loading code (Nikhil V)

- Fix and clean up system suspend statistics collection (Rafael
Wysocki)

- Simplify device suspend and resume handling in the power management
core code (Rafael Wysocki)

- Fix PCI hibernation support description (Yiwei Lin)

- Make hibernation take set_memory_ro() return values into account as
appropriate (Christophe Leroy)

ordering issue with handling it (Maulik Shah)

- Fix wake IRQs handling when pm_runtime_force_suspend() is used as a
driver's system suspend callback (Qingliang Li)

- Simplify pm_runtime_get_if_active() usage and add a replacement for
pm_runtime_put_autosuspend() (Sakari Ailus)

- Add a tracepoint for runtime_status changes tracking (Vilas Bhat)

- Fix section title markdown in the runtime PM documentation (Yiwei
Lin)

- Enable preferred core support in the amd-pstate cpufreq driver
(Meng Li)

- Fix min_perf assignment in amd_pstate_adjust_perf() and make the
min/max limit perf values in amd-pstate always stay within the
(highest perf, lowest perf) range (Tor Vic, Meng Li)

- Allow intel_pstate to assign model-specific values to strings used
in the EPP sysfs interface and make it do so on Meteor Lake
(Srinivas Pandruvada)

- Drop long-unused cpudata::prev_cummulative_iowait from the
intel_pstate cpufreq driver (Jiri Slaby)

- Prevent scaling_cur_freq from exceeding scaling_max_freq when the
latter is an inefficient frequency (Shivnandan Kumar)

- Change default transition delay in cpufreq to 2ms (Qais Yousef)

- Remove references to 10ms minimum sampling rate from comments in
the cpufreq code (Pierre Gondois)

- Honour transition_latency over transition_delay_us in cpufreq (Qais
Yousef)

- Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar)

- General enhancements / cleanups to ARM cpufreq drivers (tianyu2,
Nícolas F. R. A. Prado, Erick Archer, Arnd Bergmann, Anastasia
Belova)

- Update cpufreq-dt-platdev to block/approve devices (Richard Acayan)

- Make the SCMI cpufreq driver get a transition delay value from
firmware (Pierre Gondois)

- Prevent the haltpoll cpuidle governor from shrinking guest
poll_limit_ns below grow_start (Parshuram Sangle)

- Avoid potential overflow in integer multiplication when computing
cpuidle state parameters (C Cheng)

- Adjust MWAIT hint target C-state computation in the ACPI cpuidle
driver and in intel_idle to return a correct value for C0 (He
Rongguang)

- Address multiple issues in the TPMI RAPL driver and add support for
new platforms (Lunar Lake-M, Arrow Lake) to Intel RAPL (Zhang Rui)

- Fix freq_qos_add_request() return value check in dtpm_cpu (Daniel
Lezcano)

- Fix kernel-doc for dtpm_create_hierarchy() (Yang Li)

- Fix file leak in get_pkg_num() in x86_energy_perf_policy (Samasth
Norway Ananda)

- Fix cpupower-frequency-info.1 man page typo (Jan Kratochvil)

- Fix a couple of warnings in the OPP core code related to W=1 builds
(Viresh Kumar)

- Move dev_pm_opp_{init|free}_cpufreq_table() to pm_opp.h (Viresh
Kumar)
