Commit 5561f25b authored Jan 10, 2022 by Rafael J. Wysocki

Merge branch 'pm-cpufreq'

Merge cpufreq updates for 5.17-rc1:

 - Add new P-state driver for AMD processors (Huang Rui).

 - Fix initialization of min and max frequency QoS requests in the
   cpufreq core (Rafael Wysocki).

 - Fix EPP handling on Alder Lake in intel_pstate (Srinivas Pandruvada).

 - Make intel_pstate update cpuinfo.max_freq when notified of HWP
   capabilities changes and drop a redundant function call from that
   driver (Rafael Wysocki).

 - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
   Stephen Boyd, Vladimir Zapolskiy).

 - Fix double devm_remap() in the Mediatek cpufreq driver (Hector Yuan).

 - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz
   Luba).

 - Make cpufreq use default_groups in kobj_type (Greg Kroah-Hartman).
