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). * pm-cpufreq: (32 commits) x86, sched: Fix undefined reference to init_freq_invariance_cppc() build error cpufreq: amd-pstate: Fix Kconfig dependencies for AMD P-State cpufreq: amd-pstate: Fix struct amd_cpudata kernel-doc comment MAINTAINERS: Add AMD P-State driver maintainer entry Documentation: amd-pstate: Add AMD P-State driver introduction cpufreq: amd-pstate: Add AMD P-State performance attributes cpufreq: amd-pstate: Add AMD P-State frequencies attributes cpufreq: amd-pstate: Add boost mode support for AMD P-State cpufreq: amd-pstate: Add trace for AMD P-State module cpufreq: amd-pstate: Introduce the support for the processors with shared memory solution cpufreq: amd-pstate: Add fast switch function for AMD P-State cpufreq: amd-pstate: Introduce a new AMD P-State driver to support future processors ACPI: CPPC: Add CPPC enable register function ACPI: CPPC: Check present CPUs for determining _CPC is valid ACPI: CPPC: Implement support for SystemIO registers x86/msr: Add AMD CPPC MSR definitions x86/cpufeatures: Add AMD Collaborative Processor Performance Control feature flag cpufreq: use default_groups in kobj_type cpufreq: mediatek-hw: Fix double devm_remap in hotplug case cpufreq: intel_pstate: Update cpuinfo.max_freq on HWP_CAP changes ...
