Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-5.6-rc1
with top-most commit c102671af085aacf17219e9bdcfccddc6620a866
Merge branch 'pm-devfreq'
on top of commit 3a83c8c81c91fe10e7002c2c0e74b23e80f41f28
Merge tag 'pm-5.5-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
to receive power management updates for 5.6-rc1.
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).
Thanks!
