Merge tag 'pm-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"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)"

"1. Update devfreq core

- Add new 'name' attribute of sysfs to show the device name
: /sys/class/devfreq/devfreqX/name

- Make 'trans_stat' sysfs reset by entering zero(0)
: echo 0 > /sys/class/devfreq/devfreqX/trans_stat

- Add debugfs support with 'devfreq_summary' to show the summary
: /sys/kernel/debug/devfreq/devfreq_summary

- Change the type of time variable to 64bit to avoid overflows.

- Make separate devfreq_stats including the statistics information.

- Fix minor coding-style like indentation and kernel-doc warnings.

2. Update devfreq drivers

- Add new imx8m-ddrc.c devfreq driver for dynamic scaling of DDR frequency.
It changes the DDR frequency by using ARM SMCCC(SMC Calling Convention)
interface to control TF-A firmware.

- Add COMPILE_TEST dependency for rk3399_dmc.c.

- Clean-up code for exynos-bus.c and rk3399_dmc.c without behavior changes

3. Update devfreq-event drivers

- Fix excessive stack usage of exynos-ppmu.c and clean-up code of
rockchip-dfi.c without behavior changes."
