Pull power management updates from Rafael Wysocki:
"As is tradition, cpufreq is the part with the largest number of
updates that include core fixes and cleanups as well as updates of
several assorted drivers, but there are also quite a few updates
related to system sleep, mostly focused on asynchronous suspend and
resume of devices and on making the integration of system suspend
and resume with runtime PM easier.

Runtime PM is also updated to allow some code duplication in drivers
to be eliminated going forward and to work more consistently overall
in some cases.

Apart from that, there are some driver core updates related to PM
domains that should help to address ordering issues with devm_ cleanup
routines relying on PM domains, some assorted devfreq updates
including core fixes and cleanups, tooling updates, and documentation
and MAINTAINERS updates.

Specifics:

- Fix two initialization ordering issues in the cpufreq core and a
governor initialization error path in it, and clean it up (Lifeng
Zheng)

- Add Granite Rapids support in no-HWP mode to the intel_pstate
cpufreq driver (Li RongQing)

- Make intel_pstate always use HWP_DESIRED_PERF when operating in the
passive mode (Rafael Wysocki)

- Allow building the tegra124 cpufreq driver as a module (Aaron
Kling)

MAINTAINERS entry for cpu.rs (Abhinav Ananthu, Ritvik Gupta, Lukas
Bulwahn)

- Fix minimum performance state label error in the amd-pstate driver
documentation (Shouye Liu)

- Add the CPUFREQ_GOV_STRICT_TARGET flag to the userspace cpufreq
governor and explain HW coordination influence on it in the
documentation (Shashank Balaji)

- Fix opencoded for_each_cpu() in idle_state_valid() in the DT
cpuidle driver (Yury Norov)

- Remove info about non-existing QoS interfaces from the PM QoS
documentation (Ulf Hansson)

- Use c_* types via kernel prelude in Rust for OPP (Abhinav Ananthu)

- Add HiSilicon uncore frequency scaling driver to devfreq (Jie Zhan)

- Allow devfreq drivers to add custom sysfs ABIs (Jie Zhan)

- Simplify the sun8i-a33-mbus devfreq driver by using more devm
functions (Uwe Kleine-König)

- Fix an index typo in trans_stat() in devfreq (Chanwoo Choi)

- Check devfreq governor before using governor->name (Lifeng Zheng)

- Remove a redundant devfreq_get_freq_range() call from
devfreq_add_device() (Lifeng Zheng)

- Limit max_freq with scaling_min_freq in devfreq (Lifeng Zheng)

- Replace sscanf() with kstrtoul() in set_freq_store() (Lifeng Zheng)

- Extend the asynchronous suspend and resume of devices to handle
suppliers like parents and consumers like children (Rafael Wysocki)

- Make pm_runtime_force_resume() work for drivers that set the
DPM_FLAG_SMART_SUSPEND flag and allow PCI drivers and drivers that
collaborate with the general ACPI PM domain to set it (Rafael
Wysocki)

- Add kernel parameter to disable asynchronous suspend/resume of
devices (Tudor Ambarus)

- Drop redundant might_sleep() calls from some functions in the

pm_restore_gfp_mask() call from it (Rafael Wysocki)

- Rearrange suspend/resume error handling in the core device suspend
and resume code (Rafael Wysocki)

- Fix up white space that does not follow coding style in the
hibernation core code (Darshan Rathod)

- Document return values of suspend-related API functions in the
runtime PM framework (Sakari Ailus)

- Mark last busy stamp in multiple autosuspend-related functions in
the runtime PM framework and update its documentation (Sakari
Ailus)

- Take active children into account in pm_runtime_get_if_in_use() for
consistency (Rafael Wysocki)

Use) principle (Andy Shevchenko)

the driver core detach PM domains in device_unbind_cleanup(), and
drop the dev_pm_domain_detach() call from the platform bus type
(Claudiu Beznea)

- Improve Python binding's Makefile for cpupower (John B. Wyatt IV)

- Fix printing of CORE, CPU fields in cpupower-monitor (Gautham
Shenoy)"

PM / devfreq: Add HiSilicon uncore frequency scaling driver

Add the HiSilicon uncore frequency scaling driver for Kunpeng SoCs based on
the devfreq framework. The uncore domain contains shared computing
resources, including system interconnects and L3 cache. The uncore
frequency significantly impacts the system-wide performance as well as
power consumption. This driver adds support for runtime management of
uncore frequency from kernel and userspace. The main function includes
setting and getting frequencies, changing frequency scaling policies, and
querying the list of CPUs whose performance is significantly related to
this uncore frequency domain, etc. The driver communicates with a platform
controller through an ACPI PCC mailbox to take the actual actions of
frequency scaling.

Pull power management updates from Rafael Wysocki:
"These update several cpufreq drivers and the cpufreq core, add sysfs

from the upstream github repo.
