Merge tag 'pm-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These include cpuidle changes to use nanoseconds (instead of microseconds) as the unit of time and to simplify checks for disabled idle states in the idle loop, some cpuidle fixes and governor updates, assorted cpufreq updates (driver updates mostly and a few core fixes and cleanups), devfreq updates (dominated by the tegra30 driver changes), new CPU IDs for the RAPL power capping driver, relatively minor updates of the generic power domains (genpd) and operation performance points (OPP) frameworks, and assorted fixes and cleanups. There are also two maintainer information updates: Chanwoo Choi will be maintaining the devfreq subsystem going forward and Todd Brandt is going to maintain the pm-graph utility (created by him). Specifics: - Use nanoseconds (instead of microseconds) as the unit of time in the cpuidle core and simplify checks for disabled idle states in the idle loop (Rafael Wysocki) - Fix and clean up the teo cpuidle governor (Rafael Wysocki) - Fix the cpuidle registration error code path (Zhenzhong Duan) - Avoid excessive vmexits in the ACPI cpuidle driver (Yin Fengwei) - Extend the idle injection infrastructure to be able to measure the requested duration in nanoseconds and to allow an exit latency limit for idle states to be specified (Daniel Lezcano) - Fix cpufreq driver registration and clarify a comment in the cpufreq core (Viresh Kumar) - Add NULL checks to the show() and store() methods of sysfs attributes exposed by cpufreq (Kai Shen) - Update cpufreq drivers: * Fix for a plain int as pointer warning from sparse in intel_pstate (Jamal Shareef) * Fix for a hardcoded number of CPUs and stack bloat in the powernv driver (John Hubbard) * Updates to the ti-cpufreq driver and DT files to support new platforms and migrate bindings from opp-v1 to opp-v2 (Adam Ford, H. Nikolaus Schaller) * Merging of the arm_big_little and vexpress-spc drivers and related cleanup (Sudeep Holla) * Fix for imx's default speed grade value (Anson Huang) * Minor cleanup of the s3c64xx driver (Nathan Chancellor) * CPU speed bin detection fix for sun50i (Ondrej Jirman) - Appoint Chanwoo Choi as the new devfreq maintainer. - Update the devfreq core: * Check NULL governor in available_governors_show sysfs to prevent showing wrong governor information and fix a race condition between devfreq_update_status() and trans_stat_show() (Leonard Crestez) * Add new 'interrupt-driven' flag for devfreq governors to allow interrupt-driven governors to prevent the devfreq core from polling devices for status (Dmitry Osipenko) * Improve an error message in devfreq_add_device() (Matthias Kaehlcke) - Update devfreq drivers: * tegra30 driver fixes and cleanups (Dmitry Osipenko) * Removal of unused property from dt-binding documentation for the exynos-bus driver (Kamil Konieczny) * exynos-ppmu cleanup and DT bindings update (Lukasz Luba, Marek Szyprowski) - Add new CPU IDs for CometLake Mobile and Desktop to the Intel RAPL power capping driver (Zhang Rui) - Allow device initialization in the generic power domains (genpd) framework to be more straightforward and clean it up (Ulf Hansson) - Add support for adjusting OPP voltages at run time to the OPP framework (Stephen Boyd) - Avoid freeing memory that has never been allocated in the hibernation core (Andy Whitcroft) - Clean up function headers in a header file and coding style in the wakeup IRQs handling code (Ulf Hansson, Xiaofei Tan) - Clean up the SmartReflex adaptive voltage scaling (AVS) driver for ARM (Ben Dooks, Geert Uytterhoeven) - Wrap power management documentation to fit in 80 columns (Bjorn Helgaas) - Add pm-graph utility entry to MAINTAINERS (Todd Brandt) - Update the cpupower utility: * Fix the handling of set and info subcommands (Abhishek Goel) * Fix build warnings (Nathan Chancellor) * Improve mperf_monitor handling (Janakarajan Natarajan)" * tag 'pm-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (83 commits) PM: Wrap documentation to fit in 80 columns cpuidle: Pass exit latency limit to cpuidle_use_deepest_state() cpuidle: Allow idle injection to apply exit latency limit cpuidle: Introduce cpuidle_driver_state_disabled() for driver quirks cpuidle: teo: Avoid code duplication in conditionals cpufreq: Register drivers only after CPU devices have been registered cpuidle: teo: Avoid using "early hits" incorrectly cpuidle: teo: Exclude cpuidle overhead from computations PM / Domains: Convert to dev_to_genpd_safe() in genpd_syscore_switch() mmc: tmio: Avoid boilerplate code in ->runtime_suspend() PM / Domains: Implement the ->start() callback for genpd PM / Domains: Introduce dev_pm_domain_start() ARM: OMAP2+: SmartReflex: add omap_sr_pdata definition PM / wakeirq: remove unnecessary parentheses power: avs: smartreflex: Remove superfluous cast in debugfs_create_file() call cpuidle: Use nanoseconds as the unit of time PM / OPP: Support adjusting OPP voltages at runtime PM / core: Clean up some function headers in power.h cpufreq: Add NULL checks to show() and store() methods of cpufreq cpufreq: intel_pstate: Fix plain int as pointer warning from sparse ...
