Merge branch 'pm-cpufreq'
Merge cpufreq changes for 6.9-rc1:
- Enable preferred core support in the amd-pstate cpufreq driver (Meng
Li).
- Fix min_perf assignment in amd_pstate_adjust_perf() and make the
min/max limit perf values in amd-pstate always stay within the
(highest perf, lowest perf) range (Tor Vic, Meng Li).
- Change default transition delay in cpufreq to 2ms (Qais Yousef).
- Drop long-unused cpudata::prev_cummulative_iowait from the
intel_pstate cpufreq driver (Jiri Slaby).
- Allow intel_pstate to assign model-specific values to strings used in
the EPP sysfs interface and make it do so on Meteor Lake (Srinivas
Pandruvada).
- Remove references to 10ms minimum sampling rate from comments in the
cpufreq code (Pierre Gondois).
- Prevent scaling_cur_freq from exceeding scaling_max_freq when the
latter is an inefficient frequency (Shivnandan Kumar).
- Honour transition_latency over transition_delay_us in cpufreq (Qais
Yousef).
- Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar).
- General enhancements / cleanups to ARM cpufreq drivers (tianyu2,
Nícolas F. R. A. Prado, Erick Archer, Arnd Bergmann, Anastasia
Belova).
- Update cpufreq-dt-platdev to block/approve devices (Richard Acayan).
- Make the SCMI cpufreq driver get a transition delay value from
firmware (Pierre Gondois).
