Merge tag 'pm-5.11-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki: "These update the CPPC cpufreq driver and intel_pstate (which involves updating the cpufreq core and the schedutil governor) and make janitorial changes in the ACPI code handling processor objects. Specifics: - Rework the passive-mode "fast switch" path in the intel_pstate driver to allow it receive the minimum (required) and target (desired) performance information from the schedutil governor so as to avoid running some workloads too fast (Rafael Wysocki). - Make the intel_pstate driver allow the policy max limit to be increased after the guaranteed performance value for the given CPU has increased (Rafael Wysocki). - Clean up the handling of CPU coordination types in the CPPC cpufreq driver and make it export frequency domains information to user space via sysfs (Ionela Voinescu). - Fix the ACPI code handling processor objects to use a correct coordination type when it fails to map frequency domains and drop a redundant CPU map initialization from it (Ionela Voinescu, Punit Agrawal)" * tag 'pm-5.11-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: intel_pstate: Use most recent guaranteed performance values cpufreq: intel_pstate: Implement the ->adjust_perf() callback cpufreq: Add special-purpose fast-switching callback for drivers cpufreq: schedutil: Add util to struct sg_cpu cppc_cpufreq: replace per-cpu data array with a list cppc_cpufreq: expose information on frequency domains cppc_cpufreq: clarify support for coordination types cppc_cpufreq: use policy->cpu as driver of frequency setting ACPI: processor: fix NONE coordination for domain mapping failure
