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:
- Rework the handling of disabled turbo in the intel_pstate driver
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)
- Update MAINTAINERS entry for amd-pstate to add two new
submaintainers and a designated reviewer (Huang Rui)
- Clean up the amd-pstate driver and update its documentation
(Gautham Shenoy)
- Fix the highest frequency issue in the amd-pstate driver which
limits performance (Perry Yuan)
- Enable CPPC v2 for certain processors in the family 17H, as
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)
- brcmstb-avs: ISO C90 forbids mixed declarations (Portia Stephens)
- mediatek cpufreq: Add support for MT7988A (Sam Shih)
- cpufreq-qcom-hw: Add SM4450 compatibles in DT bindings (Tengfei
Fan)
- Fix struct cpudata::epp_cached kernel-doc in the intel_pstate
cpufreq driver (Jeff Johnson)
- Fix kerneldoc description of ladder_do_selection() (Jeff Johnson)
- Convert the cpuidle kirkwood driver to platform remove callback
returning void (Yangtao Li)
- Replace deprecated strncpy() with strscpy() in the hibernation core
code (Justin Stitt)
- Use %ps to simplify debug output in the core system-wide suspend
and resume code (Len Brown)
- Remove unnecessary else from device_init_wakeup() and make
device_wakeup_disable() return void (Dhruva Gole)
- Enable PMU support in the Intel TPMI RAPL driver (Zhang Rui)
- Add support for ArrowLake-H platform to the Intel RAPL driver
(Zhang Rui)
- Avoid explicit cpumask allocation on stack in DTPM (Dawei Li)
- Make the Samsung exynos-asv driver update the Energy Model after
adjusting voltage on top of some preliminary changes of the OPP and
Enery Model generic code (Lukasz Luba)
- Remove a reference to a function that has been dropped from the
power management documentation (Bjorn Helgaas)
- Convert the platfrom remove callback to .remove_new for the
exyno-nocp, exynos-ppmu, mtk-cci-devfreq, sun8i-a33-mbus, and
rk3399_dmc devfreq drivers (Uwe Kleine-König)
- Use DEFINE_SIMPLE_PM_OPS for exyno-bus.c driver (Anand Moon)"
