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 (Nícolas 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)"
