Merge tag 'pm-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These update PCI and ACPI power management (improved handling of ACPI power resources and PCIe link delays, fixes related to corner cases, hibernation handling rework), fix and extend the operating performance points (OPP) framework, add new cpufreq drivers for Raspberry Pi and imx8m chips, update some other cpufreq drivers, clean up assorted pieces of PM code and documentation and update tools. Specifics: - Improve the handling of shared ACPI power resources in the PCI bus type layer (Mika Westerberg). - Make the PCI layer take link delays required by the PCIe spec into account as appropriate and avoid polling devices in D3cold for PME (Mika Westerberg). - Fix some corner case issues in ACPI device power management and in the PCI bus type layer, optimiza and clean up the handling of runtime-suspended PCI devices during system-wide transitions to sleep states (Rafael Wysocki). - Rework hibernation handling in the ACPI core and the PCI bus type to resume runtime-suspended devices before hibernation (which allows some functional problems to be avoided) and fix some ACPI power management issues related to hiberation (Rafael Wysocki). - Extend the operating performance points (OPP) framework to support a wider range of devices (Rajendra Nayak, Stehpen Boyd). - Fix issues related to genpd_virt_devs and issues with platforms using the set_opp() callback in the OPP framework (Viresh Kumar, Dmitry Osipenko). - Add new cpufreq driver for Raspberry Pi (Nicolas Saenz Julienne). - Add new cpufreq driver for imx8m and imx7d chips (Leonard Crestez). - Fix and clean up the pcc-cpufreq, brcmstb-avs-cpufreq, s5pv210, and armada-37xx cpufreq drivers (David Arcari, Florian Fainelli, PaweĊ‚ Chmiel, YueHaibing). - Clean up and fix the cpufreq core (Viresh Kumar, Daniel Lezcano). - Fix minor issue in the ACPI system sleep support code and export one function from it (Lenny Szubowicz, Dexuan Cui). - Clean up assorted pieces of PM code and documentation (Kefeng Wang, Andy Shevchenko, Bart Van Assche, Greg Kroah-Hartman, Fuqian Huang, Geert Uytterhoeven, Mathieu Malaterre, Rafael Wysocki). - Update the pm-graph utility to v5.4 (Todd Brandt). - Fix and clean up the cpupower utility (Abhishek Goel, Nick Black)" * tag 'pm-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (57 commits) ACPI: PM: Make acpi_sleep_state_supported() non-static PM: sleep: Drop dev_pm_skip_next_resume_phases() ACPI: PM: Unexport acpi_device_get_power() Documentation: ABI: power: Add missing newline at end of file ACPI: PM: Drop unused function and function header ACPI: PM: Introduce "poweroff" callbacks for ACPI PM domain and LPSS ACPI: PM: Simplify and fix PM domain hibernation callbacks PCI: PM: Simplify bus-level hibernation callbacks PM: ACPI/PCI: Resume all devices during hibernation cpufreq: Avoid calling cpufreq_verify_current_freq() from handle_update() cpufreq: Consolidate cpufreq_update_current_freq() and __cpufreq_get() kernel: power: swap: use kzalloc() instead of kmalloc() followed by memset() cpufreq: Don't skip frequency validation for has_target() drivers PCI: PM/ACPI: Refresh all stale power state data in pci_pm_complete() PCI / ACPI: Add _PR0 dependent devices ACPI / PM: Introduce concept of a _PR0 dependent device PCI / ACPI: Use cached ACPI device state to get PCI device power state ACPI: PM: Allow transitions to D0 to occur in special cases ACPI: PM: Avoid evaluating _PS3 on transitions from D3hot to D3cold cpufreq: Use has_target() instead of !setpolicy ...
