Pull power management updates from Rafael Wysocki:
"These add support for 'artificial' Energy Models in which power
numbers for different entities may be in different scales, add support
for some new hardware, fix bugs and clean up code in multiple places.

Specifics:

- Update the Energy Model support code to allow the Energy Model to
be artificial, which means that the power values may not be on a
uniform scale with other devices providing power information, and
update the cpufreq_cooling and devfreq_cooling thermal drivers to
support artificial Energy Models (Lukasz Luba).

- Make DTPM check the Energy Model type (Lukasz Luba).

- Fix policy counter decrementation in cpufreq if Energy Model is in
use (Pierre Gondois).

- Add CPU-based scaling support to passive devfreq governor (Saravana
Kannan, Chanwoo Choi).

- Update the rk3399_dmc devfreq driver (Brian Norris).

- Export dev_pm_ops instead of suspend() and resume() in the IIO
chemical scd30 driver (Jonathan Cameron).

- Add namespace variants of EXPORT[_GPL]_SIMPLE_DEV_PM_OPS and
PM-runtime counterparts (Jonathan Cameron).

- Move symbol exports in the IIO chemical scd30 driver into the
IIO_SCD30 namespace (Jonathan Cameron).

- Avoid device PM-runtime usage count underflows (Rafael Wysocki).

- Allow dynamic debug to control printing of PM messages (David
Cohen).

- Fix some kernel-doc comments in hibernation code (Yang Li, Haowen
Bai).

- Preserve ACPI-table override during hibernation (Amadeusz
Sławiński).

- Improve support for suspend-to-RAM for PSCI OSI mode (Ulf Hansson).

- Make Intel RAPL power capping driver support the RaptorLake and
AlderLake N processors (Zhang Rui, Sumeet Pawnikar).

- Remove redundant store to value after multiply in the RAPL power
capping driver (Colin Ian King).

- Add AlderLake processor support to the intel_idle driver (Zhang
Rui).

- Fix regression leading to no genpd governor in the PSCI cpuidle
driver and fix the riscv-sbi cpuidle driver to allow a genpd
governor to be used (Ulf Hansson).

- Fix cpufreq governor clean up code to avoid using kfree() directly
to free kobject-based items (Kevin Hao).

- Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe
Leroy).

- Make intel_pstate notify frequency invariance code when no_turbo is
turned on and off (Chen Yu).

- Add Sapphire Rapids OOB mode support to intel_pstate (Srinivas
Pandruvada).

- Make cpufreq avoid unnecessary frequency updates due to mismatch
between hardware and the frequency table (Viresh Kumar).

- Make remove_cpu_dev_symlink() clear the real_cpus mask to simplify
code (Viresh Kumar).

- Rearrange cpufreq_offline() and cpufreq_remove_dev() to make the
calling convention for some driver callbacks consistent (Rafael
Wysocki).

- Avoid accessing half-initialized cpufreq policies from the show()
and store() sysfs functions (Schspa Shi).

- Rearrange cpufreq_offline() to make the calling convention for some
driver callbacks consistent (Schspa Shi).

Merge tag 'devfreq-next-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq changes for 5.19-rc1 from Chanwoo Choi:

"1. Update devfreq core

- Add cpu based scaling support to passive governor. Some device like
cache might require the dynamic frequency scaling. But, it has very
tightly to cpu frequency. So that use passive governor to scale
the frequency according to current cpu frequency.

To decide the frequency of the device, the governor does one of the following:
: Derives the optimal devfreq device opp from required-opps property of
the parent cpu opp_table.

: Scales the device frequency in proportion to the CPU frequency. So, if
the CPUs are running at their max frequency, the device runs at its
max frequency. If the CPUs are running at their min frequency, the
device runs at its min frequency. It is interpolated for frequencies
in between.

2. Update devfreq drivers

- Update rk3399_dmc.c as following:

: Convert dt-binding document to YAML and deprecate unused properties.

: Use Hz units for the device-tree properties of rk3399_dmc.

: rk3399_dmc is able to set the idle time before changing the dmc clock.
Specify idle time parameters by using nano-second unit on dt bidning.

: Add new disable-freq properties to optimize the power-saving feature
of rk3399_dmc.

: Disable devfreq-event device on remove() to fix unbalanced
enable-disable count.

: Use devm_pm_opp_of_add_table()

: Block PMU (Power-Management Unit) transitions when scaling frequency
by ARM Trust Firmware in order to fix the conflict between PMU and DMC
(Dynamic Memory Controller)."

PM / devfreq: Add cpu based scaling support to passive governor

Many CPU architectures have caches that can scale independent of the
CPUs. Frequency scaling of the caches is necessary to make sure that the
cache is not a performance bottleneck that leads to poor performance and
power. The same idea applies for RAM/DDR.

To achieve this, this patch adds support for cpu based scaling to the
passive governor. This is accomplished by taking the current frequency
of each CPU frequency domain and then adjust the frequency of the cache
(or any devfreq device) based on the frequency of the CPUs. It listens
to CPU frequency transition notifiers to keep itself up to date on the
current CPU frequency.

To decide the frequency of the device, the governor does one of the
following:
* Derives the optimal devfreq device opp from required-opps property of
the parent cpu opp_table.

* Scales the device frequency in proportion to the CPU frequency. So, if
the CPUs are running at their max frequency, the device runs at its
max frequency. If the CPUs are running at their min frequency, the
device runs at its min frequency. It is interpolated for frequencies
in between.
