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).
