Merge branch 'pm-cpufreq'

Merge cpufreq updates for 6.10:

 - 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: Add support for opp_supported_hw, H616 platform and general
   cleanups (Andre Przywara, Martin Botka, Brandon Cheo Fusi, Dan
   Carpenter, Viresh Kumar).

 - CPPC: Fix possible null pointer dereference (Aleksandr Mishin).

 - Eliminate uses of of_node_put() (Javier Carrasco, and Shivani Gupta).

 - brcmstb-avs: ISO C90 forbids mixed declarations (Portia Stephens).

 - mediatek: 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).
