    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).
