Merge branch 'pm-cpufreq'

Merge cpufreq updates for 6.15-rc1:

 - Manage sysfs attributes and boost frequencies efficiently from
   cpufreq core to reduce boilerplate code from drivers (Viresh Kumar).

 - Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
   Dhananjay Ugwekar, Imran Shaik, and zuoqian).

 - Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
   Bai).

 - cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski).

 - Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng).

 - Optimize the amd-pstate driver to avoid cases where call paths end
   up calling the same writes multiple times and needlessly caching
   variables through code reorganization, locking overhaul and tracing
   adjustments (Mario Limonciello, Dhananjay Ugwekar).

 - Make it possible to avoid enabling capacity-aware scheduling (CAS) in
   the intel_pstate driver and relocate a check for out-of-band (OOB)
   platform handling in it to make it detect OOB before checking HWP
   availability (Rafael Wysocki).

 - Fix dbs_update() to avoid inadvertent conversions of negative integer
   values to unsigned int which causes CPU frequency selection to be
   inaccurate in some cases when the "conservative" cpufreq governor is
   in use (Jie Zhan).
