"These are mostly ARM cpufreq driver updates plus a cpufreq core
cleanup, an ARM-wide change to make schedutil the default scaling
governor, an intel_pstate driver fix and some runtime PM changes

- Add adaptive voltage scaling (AVS) support to the brcmstb cpufreq
driver and clean it up (Florian Fainelli, Markus Mayer).

- Add a new Tegra cpufreq driver and clean up the existing one (Jon
Hunter, Sumit Gupta).

- Add bandwidth level support to the Qcom cpufreq driver along with
OPP changes (Sibi Sankar).

- Clean up the sti, cpufreq-dt, ap806, CPPC cpufreq drivers (Viresh
Kumar, Lee Jones, Ivan Kokshaysky, Sven Auhagen, Xin Hao).

- Make schedutil the default governor for ARM (Valentin Schneider).

- Fix dependency issues for the imx cpufreq driver (Walter Lozano).

- Clean up cached_resolved_idx handlihng in the cpufreq core (Viresh

- Fix the intel_pstate driver to use the correct maximum frequency
value when MSR_TURBO_RATIO_LIMIT is 0 (Srinivas Pandruvada).

- Provide kenrneldoc comments for multiple runtime PM helpers and
improve the pm_runtime_get_if_active() kerneldoc (Rafael Wysocki)"

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)"

cpufreq: brcmstb-avs: fix imbalance of cpufreq policy refcount

brcm_avs_cpufreq_get() calls cpufreq_cpu_get() to get the cpufreq
policy, meanwhile, it also increments the kobject reference count
to mark it busy. However, a corresponding call of cpufreq_cpu_put()
is ignored to decrement the kobject reference count back, which may
lead to a potential stuck risk that the cpuhp thread deadly waits
for dropping of kobject refcount when cpufreq policy free.

With this patch, the cpuhp thread can be easily exercised by
attempting to force an unbind of the CPUfreq driver.
