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)"
