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)" * tag 'pm-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (68 commits) PM / devfreq: exynos: Use DEFINE_SIMPLE_DEV_PM_OPS for PM functions PM / devfreq: rk3399_dmc: Convert to platform remove callback returning void PM / devfreq: sun8i-a33-mbus: Convert to platform remove callback returning void PM / devfreq: mtk-cci: Convert to platform remove callback returning void PM / devfreq: exynos-ppmu: Convert to platform remove callback returning void PM / devfreq: exynos-nocp: Convert to platform remove callback returning void cpufreq: amd-pstate: fix the highest frequency issue which limits performance cpufreq: intel_pstate: fix struct cpudata::epp_cached kernel-doc cpuidle: ladder: fix ladder_do_selection() kernel-doc powercap: intel_rapl_tpmi: Enable PMU support powercap: intel_rapl: Introduce APIs for PMU support PM: hibernate: replace deprecated strncpy() with strscpy() cpufreq: Fix up printing large CPU numbers and frequency values MAINTAINERS: cpufreq: amd-pstate: Add co-maintainers and reviewer cpufreq: amd-pstate: remove unused variable lowest_nonlinear_freq cpufreq: amd-pstate: fix code format problems cpufreq: amd-pstate: Add quirk for the pstate CPPC capabilities missing cppc_acpi: print error message if CPPC is unsupported cpufreq: amd-pstate: get transition delay and latency value from ACPI tables cpufreq: amd-pstate: Bail out if min/max/nominal_freq is 0 ...
