Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.10-rc1

with top-most commit de1c2722e07819c7ea65bb4bf37a2cfe2556095b

 Merge branches 'pm-em' and 'pm-docs'

on top of commit dd5a440a31fae6e459c0d6271dddd62825505361

 Linux 6.9-rc7

to receive power management updates for 6.10-rc1.

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-K=C3=B6nig).

 - Use DEFINE_SIMPLE_PM_OPS for exyno-bus.c driver (Anand Moon).

Thanks!
