Pull power management updates from Rafael Wysocki: "These add a new cpufreq driver for Loongson-3, add support for new features in the intel_pstate (Lunar Lake and Arrow Lake platforms, OOB mode for Emerald Rapids, highest performance change interrupt), amd-pstate (fast CPPC) and sun50i (Allwinner H700 speed bin) cpufreq drivers, simplify the cpufreq driver interface, simplify the teo cpuidle governor, adjust the pm-graph utility for a new version of Python, address issues and clean up code. Specifics: - Add Loongson-3 CPUFreq driver support (Huacai Chen) - Add support for the Arrow Lake and Lunar Lake platforms and the out-of-band (OOB) mode on Emerald Rapids to the intel_pstate cpufreq driver, make it support the highest performance change interrupt and clean it up (Srinivas Pandruvada) - Switch cpufreq to new Intel CPU model defines (Tony Luck) - Simplify the cpufreq driver interface by switching the .exit() driver callback to the void return data type (Lizhe, Viresh Kumar) - Make cpufreq_boost_enabled() return bool (Dhruva Gole) - Add fast CPPC support to the amd-pstate cpufreq driver, address multiple assorted issues in it and clean it up (Perry Yuan, Mario Limonciello, Dhananjay Ugwekar, Meng Li, Xiaojian Du) - Add Allwinner H700 speed bin to the sun50i cpufreq driver (Ryan Walklin) - Fix memory leaks and of_node_put() usage in the sun50i and qcom-nvmem cpufreq drivers (Javier Carrasco) - Clean up the sti and dt-platdev cpufreq drivers (Jeff Johnson, Raphael Gallais-Pou) - Fix deferred probe handling in the TI cpufreq driver and wrong return values of ti_opp_supply_probe(), and add OPP tables for the AM62Ax and AM62Px SoCs to it (Bryan Brattlof, Primoz Fiser) - Avoid overflow of target_freq in .fast_switch() in the SCMI cpufreq driver (Jagadeesh Kona) - Use dev_err_probe() in every error path in probe in the Mediatek cpufreq driver (NĂ­colas Prado) - Fix kernel-doc param for longhaul_setstate in the longhaul cpufreq driver (Yang Li) - Fix system resume handling in the CPPC cpufreq driver (Riwen Lu) - Improve the teo cpuidle governor and clean up leftover comments from the menu cpuidle governor (Christian Loehle) - Clean up a comment typo in the teo cpuidle governor (Atul Kumar Pant) - Add missing MODULE_DESCRIPTION() macro to cpuidle haltpoll (Jeff Johnson) - Switch the intel_idle driver to new Intel CPU model defines (Tony Luck) - Switch the Intel RAPL driver new Intel CPU model defines (Tony Luck) - Simplify if condition in the idle_inject driver (Thorsten Blum) - Fix missing cleanup on error in _opp_attach_genpd() (Viresh Kumar) - Introduce an OF helper function to inform if required-opps is used and drop a redundant in-parameter to _set_opp_level() (Ulf Hansson) - Update pm-graph to v5.12 which includes fixes and major code revamp for python3.12 (Todd Brandt) - Address several assorted issues in the cpupower utility (Roman Storozhenko)" * tag 'pm-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (77 commits) cpufreq: sti: fix build warning cpufreq: mediatek: Use dev_err_probe in every error path in probe cpufreq: Add Loongson-3 CPUFreq driver support cpufreq: Make cpufreq_driver->exit() return void cpufreq/amd-pstate: Fix the scaling_max_freq setting on shared memory CPPC systems cpufreq/amd-pstate-ut: Convert nominal_freq to khz during comparisons cpufreq: pcc: Remove empty exit() callback cpufreq: loongson2: Remove empty exit() callback cpufreq: nforce2: Remove empty exit() callback cpupower: fix lib default installation path cpufreq: docs: Add missing scaling_available_frequencies description cpuidle: teo: Don't count non-existent intercepts cpupower: Disable direct build of the 'bench' subproject cpuidle: teo: Remove recent intercepts metric Revert: "cpuidle: teo: Introduce util-awareness" cpufreq: make cpufreq_boost_enabled() return bool cpufreq: intel_pstate: Support highest performance change interrupt x86/cpufeatures: Add HWP highest perf change feature flag Documentation: cpufreq: amd-pstate: update doc for Per CPU boost control method cpufreq: amd-pstate: Cap the CPPC.max_perf to nominal_perf if CPB is off ...
