These add ACPI support to the intel_idle driver along with an admin guide document for it, add support for CPR (Core Power Reduction) to the AVS (Adaptive Voltage Scaling) subsystem, add new hardware support in a few places, add some new sysfs attributes, debugfs files and tracepoints, fix bugs and clean up a bunch of things all over. Specifics: - Update the ACPI processor driver in order to export acpi_processor_evaluate_cst() to the code outside of it, add ACPI support to the intel_idle driver based on that and clean up that driver somewhat (Rafael Wysocki). - Add an admin guide document for the intel_idle driver (Rafael Wysocki). - Clean up cpuidle core and drivers, enable compilation testing for some of them (Benjamin Gaignard, Krzysztof Kozlowski, Rafael Wysocki, Yangtao Li). - Fix reference counting of OPP (operating performance points) table structures (Viresh Kumar). - Add support for CPR (Core Power Reduction) to the AVS (Adaptive Voltage Scaling) subsystem (Niklas Cassel, Colin Ian King, YueHaibing). - Add support for TigerLake Mobile and JasperLake to the Intel RAPL power capping driver (Zhang Rui). - Update cpufreq drivers: * Add i.MX8MP support to imx-cpufreq-dt (Anson Huang). * Fix usage of a macro in loongson2_cpufreq (Alexandre Oliva). * Fix cpufreq policy reference counting issues in s3c and brcmstb-avs (chenqiwu). * Fix ACPI table reference counting issue and HiSilicon quirk handling in the CPPC driver (Hanjun Guo). * Clean up spelling mistake in intel_pstate (Harry Pan). * Convert the kirkwood and tegra186 drivers to using devm_platform_ioremap_resource() (Yangtao Li). - Update devfreq core: * Add 'name' sysfs attribute for devfreq devices (Chanwoo Choi). * Clean up the handing of transition statistics and allow them to be reset by writing 0 to the 'trans_stat' devfreq device attribute in sysfs (Kamil Konieczny). * Add 'devfreq_summary' to debugfs (Chanwoo Choi). * Clean up kerneldoc comments and Kconfig indentation (Krzysztof Kozlowski, Randy Dunlap). - Update devfreq drivers: * Add dynamic scaling for the imx8m DDR controller and clean up imx8m-ddrc (Leonard Crestez, YueHaibing). * Fix DT node reference counting and nitialization error code path in rk3399_dmc and add COMPILE_TEST and HAVE_ARM_SMCCC dependency for it (Chanwoo Choi, Yangtao Li). * Fix DT node reference counting in rockchip-dfi and make it use devm_platform_ioremap_resource() (Yangtao Li). * Fix excessive stack usage in exynos-ppmu (Arnd Bergmann). * Fix initialization error code paths in exynos-bus (Yangtao Li). * Clean up exynos-bus and exynos somewhat (Artur Świgoń, Krzysztof Kozlowski). - Add tracepoints for tracking usage_count updates unrelated to status changes in PM-runtime (Michał Mirosław). - Add sysfs attribute to control the "sync on suspend" behavior during system-wide suspend (Jonas Meurer). - Switch system-wide suspend tests over to 64-bit time (Alexandre Belloni). - Make wakeup sources statistics in debugfs cover deleted ones which used to be the case some time ago (zhuguangqing). - Clean up computations carried out during hibernation, update messages related to hibernation and fix a spelling mistake in one of them (Wen Yang, Luigi Semenzato, Colin Ian King). - Add mailmap entry for maintainer e-mail address that has not been functional for several years (Rafael Wysocki).
