Pull more power management updates from Rafael Wysocki:
"These add support for new hardware (ap807 and AM62A7), fix several
issues in cpufreq drivers and in the operating performance points
(OPP) framework, fix up intel_idle after recent changes and add
documentation.
Specifics:
- Add missing __init annotation to one function in the intel_idle
drvier (Rafael Wysocki)
- Make intel_pstate use a correct scaling factor when mapping HWP
performance levels to frequency values on hybrid-capable systems
with disabled E-cores (Srinivas Pandruvada)
- Fix Kconfig dependencies of the cpufreq-dt-platform driver (Viresh
Kumar)
- Add support to build cpufreq-dt-platdev as a module (Zhipeng Wang)
- Don't allocate Sparc's cpufreq_driver dynamically (Viresh Kumar)
- Add support for TI's AM62A7 platform (Vibhore Vardhan)
- Add support for Armada's ap807 platform (Russell King (Oracle))
- Add support for StarFive JH7110 SoC (Mason Huo)
- Fix voltage selection for Mediatek Socs (Daniel Golle)
- Fix error handling in Tegra's cpufreq driver (Christophe JAILLET)
- Document Qualcomm's IPQ8074 in DT bindings (Robert Marko)
- Don't warn for disabling a non-existing frequency for imx6q cpufreq
driver (Christoph Niedermaier)
- Use dev_err_probe() in Qualcomm's cpufreq driver (Andrew Halaney)
- Simplify performance state related logic in the OPP core (Viresh
Kumar)
- Fix use-after-free and improve locking around lazy_opp_tables
(Viresh Kumar, Stephan Gerhold)
- Minor cleanups - using dev_err_probe() and rate-limiting debug
messages (Andrew Halaney, Adrián Larumbe)"
