Linus Torvalds 0c181b1d97 Power management updates for 6.10-rc1
- 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

  - 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).

    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).

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.
