Merge tag 'pm-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These are PM-runtime framework changes to use ktime instead of jiffies for accounting, new PM core flag to mark devices that don't need any form of power management, cpuidle updates including driver API documentation and a new governor, cpufreq updates including a new driver for Armada 8K, thermal cleanups and more, some energy-aware scheduling (EAS) enabling changes, new chips support in the intel_idle and RAPL drivers and assorted cleanups in some other places. Specifics: - Update the PM-runtime framework to use ktime instead of jiffies for accounting (Thara Gopinath, Vincent Guittot) - Optimize the autosuspend code in the PM-runtime framework somewhat (Ladislav Michl) - Add a PM core flag to mark devices that don't need any form of power management (Sudeep Holla) - Introduce driver API documentation for cpuidle and add a new cpuidle governor for tickless systems (Rafael Wysocki) - Add Jacobsville support to the intel_idle driver (Zhang Rui) - Clean up a cpuidle core header file and the cpuidle-dt and ACPI processor-idle drivers (Yangtao Li, Joseph Lo, Yazen Ghannam) - Add new cpufreq driver for Armada 8K (Gregory Clement) - Fix and clean up cpufreq core (Rafael Wysocki, Viresh Kumar, Amit Kucheria) - Add support for light-weight tear-down and bring-up of CPUs to the cpufreq core and use it in the cpufreq-dt driver (Viresh Kumar) - Fix cpu_cooling Kconfig dependencies, add support for CPU cooling auto-registration to the cpufreq core and use it in multiple cpufreq drivers (Amit Kucheria) - Fix some minor issues and do some cleanups in the davinci, e_powersaver, ap806, s5pv210, qcom and kryo cpufreq drivers (Bartosz Golaszewski, Gustavo Silva, Julia Lawall, Paweł Chmiel, Taniya Das, Viresh Kumar) - Add a Hisilicon CPPC quirk to the cppc_cpufreq driver (Xiongfeng Wang) - Clean up the intel_pstate and acpi-cpufreq drivers (Erwan Velu, Rafael Wysocki) - Clean up multiple cpufreq drivers (Yangtao Li) - Update cpufreq-related MAINTAINERS entries (Baruch Siach, Lukas Bulwahn) - Add support for exposing the Energy Model via debugfs and make multiple cpufreq drivers register an Energy Model to support energy-aware scheduling (Quentin Perret, Dietmar Eggemann, Matthias Kaehlcke) - Add Ice Lake mobile and Jacobsville support to the Intel RAPL power-capping driver (Gayatri Kammela, Zhang Rui) - Add a power estimation helper to the operating performance points (OPP) framework and clean up a core function in it (Quentin Perret, Viresh Kumar) - Make minor improvements in the generic power domains (genpd), OPP and system suspend frameworks and in the PM core (Aditya Pakki, Douglas Anderson, Greg Kroah-Hartman, Rafael Wysocki, Yangtao Li)" * tag 'pm-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (80 commits) cpufreq: kryo: Release OPP tables on module removal cpufreq: ap806: add missing of_node_put after of_device_is_available cpufreq: acpi-cpufreq: Report if CPU doesn't support boost technologies cpufreq: Pass updated policy to driver ->setpolicy() callback cpufreq: Fix two debug messages in cpufreq_set_policy() cpufreq: Reorder and simplify cpufreq_update_policy() cpufreq: Add kerneldoc comments for two core functions PM / core: Add support to skip power management in device/driver model cpufreq: intel_pstate: Rework iowait boosting to be less aggressive cpufreq: intel_pstate: Eliminate intel_pstate_get_base_pstate() cpufreq: intel_pstate: Avoid redundant initialization of local vars powercap/intel_rapl: add Ice Lake mobile ACPI / processor: Set P_LVL{2,3} idle state descriptions cpufreq / cppc: Work around for Hisilicon CPPC cpufreq ACPI / CPPC: Add a helper to get desired performance cpufreq: davinci: move configuration to include/linux/platform_data cpufreq: speedstep: convert BUG() to BUG_ON() cpufreq: powernv: fix missing check of return value in init_powernv_pstates() cpufreq: longhaul: remove unneeded semicolon cpufreq: pcc-cpufreq: remove unneeded semicolon ..
