"Once again, the changes are dominated by cpufreq updates

Merge tag 'pm-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.

Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).

There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.

In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.

Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.

Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.

Specifics:

- Fix potential division-by-zero error in em_compute_costs() (Yaxiong
Tian)

- Fix typos in energy model documentation and example driver code
(Moon Hee Lee, Atul Kumar Pant)

- Rearrange the energy model management code and add a new function
for adjusting a CPU energy model after adjusting the capacity of
the given CPU to it (Rafael Wysocki)

- Refactor cpufreq_online(), add and use cpufreq policy locking
guards, use __free() in policy reference counting, and clean up
core cpufreq code on top of that (Rafael Wysocki)

- Fix boost handling on CPU suspend/resume and sysfs updates (Viresh
Kumar)

- Fix des_perf clamping with max_perf in amd_pstate_update()
(Dhananjay Ugwekar)

- Add offline, online and suspend callbacks to the amd-pstate driver,
rename and use the existing amd_pstate_epp callbacks in it
(Dhananjay Ugwekar)

- Add support for the "Requested CPU Min frequency" BIOS option to
the amd-pstate driver (Dhananjay Ugwekar)

- Reset amd-pstate driver mode after running selftests (Swapnil
Sapkal)

- Avoid shadowing ret in amd_pstate_ut_check_driver() (Nathan
Chancellor)

- Add helper for governor checks to the schedutil cpufreq governor
and move cpufreq-specific EAS checks to cpufreq (Rafael Wysocki)

- Populate the cpu_capacity sysfs entries from the intel_pstate
driver after registering asym capacity support (Ricardo Neri)

- Add support for enabling Energy-aware scheduling (EAS) to the
intel_pstate driver when operating in the passive mode on a hybrid
platform (Rafael Wysocki)

- Drop redundant cpus_read_lock() from store_local_boost() in the
cpufreq core (Seyediman Seyedarab)

- Replace sscanf() with kstrtouint() in the cpufreq code and use a
symbol instead of a raw number in it (Bowen Yu)

- Add support for autonomous CPU performance state selection to the
CPPC cpufreq driver (Lifeng Zheng)

- OPP: Add dev_pm_opp_set_level() (Praveen Talari)

- Introduce scope-based cleanup headers and mutex locking guards in
OPP core (Viresh Kumar)

- Switch OPP to use kmemdup_array() (Zhang Enpei)

- Optimize bucket assignment when next_timer_ns equals KTIME_MAX in
the menu cpuidle governor (Zhongqiu Han)

- Convert the cpuidle PSCI driver to a faux device one (Sudeep Holla)

- Add C1 demotion on/off sysfs knob to the intel_idle driver (Artem
Bityutskiy)

- Fix typos in two comments in the teo cpuidle governor (Atul Kumar
Pant)

- Fix denying of auto suspend in pm_suspend_timer_fn() (Charan Teja
Kalla)

- Move debug runtime PM attributes to runtime_attrs[] (Rafael
Wysocki)

- Add new devm_ functions for enabling runtime PM and runtime PM
reference counting (Bence Csókás)

- Remove size arguments from strscpy() calls in the hibernation core
code (Thorsten Blum)

- Adjust the handling of devices with asynchronous suspend enabled
during system suspend and resume to start resuming them immediately
after resuming their parents and to start suspending such a device
immediately after suspending its first child (Rafael Wysocki)

- Adjust messages printed during tasks freezing to avoid using
pr_cont() (Andrew Sayers, Paul Menzel)

- Clean up unnecessary usage of !! in pm_print_times_init() (Zihuan
Zhang)

- Add missing wakeup source attribute relax_count to sysfs and remove
the space character at the end ofi the string produced by
pm_show_wakelocks() (Zijun Hu)

- Add configurable pm_test delay for hibernation (Zihuan Zhang)

- Disable asynchronous suspend in ucsi_ccg_probe() to prevent the
cypd4226 device on Tegra boards from suspending prematurely (Jon
Hunter)

- Unbreak printing PM debug messages during hibernation and clean up
some related code (Rafael Wysocki)

- Add a systemd service to run cpupower and change cpupower binding's
Makefile to use -lcpupower (John B. Wyatt IV, Francesco Poli)"

Merge tag 'pm-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"The majority of changes here are cpufreq updates which are dominated
by amd-pstate driver changes, like in the previous cycle. Moreover,
changes related to amd-pstate are also the majority of cpupower
utility updates.

Included are some pieces of new hardware support, like the addition of
Clearwater Forest processors support to intel_idle, new cpufreq driver
for Airoha SoCs, and Apple cpufreq driver extensions to support more
SoCs. The intel_pstate driver is also extended to be able to support
new platforms by using ACPI CPPC to compute scaling factors between
HWP performance states and frequency.

The rest is mostly fixes and cleanups in assorted pieces of power
management code.

Specifics:

- Use str_enable_disable()-like helpers in cpufreq (Krzysztof
Kozlowski)

- Extend the Apple cpufreq driver to support more SoCs (Hector
Martin, Nick Chan)

- Add new cpufreq driver for Airoha SoCs (Christian Marangi)

driver (Naresh Solanki)

- Add ftrace event to the amd-pstate driver for active mode (Mario
Limonciello)

- Set default EPP policy on Ryzen processors in amd-pstate (Mario
Limonciello)

- Clean up the amd-pstate cpufreq driver and optimize it to increase
code reuse (Mario Limonciello, Dhananjay Ugwekar)

- Use CPPC to get scaling factors between HWP performance levels and
frequency in the intel_pstate driver and make it stop using a
built-in scaling factor for Arrow Lake processors (Rafael Wysocki)

- Make intel_pstate initialize epp_policy to CPUFREQ_POLICY_UNKNOWN
for consistency with CPU offline (Christian Loehle)

- Fix superfluous updates caused by need_freq_update in the schedutil
cpufreq governor (Sultan Alsawaf)

- Allow configuring the system suspend-resume (DPM) watchdog to warn
earlier than panic (Douglas Anderson)

- Implement devm_device_init_wakeup() helper and introduce a device-
managed variant of dev_pm_set_wake_irq() (Joe Hattori, Peng Fan)

- Remove direct inclusions of 'pm_wakeup.h' which should be only
included via 'device.h' (Wolfram Sang)

- Clean up two comments in the core system-wide PM code (Rafael
Wysocki, Randy Dunlap)

- Add Clearwater Forest processor support to the intel_idle cpuidle
driver (Artem Bityutskiy)

header changes for cpufreq.h to SWIG bindings in cpupower (John B.
Wyatt IV)

- Add missing residency header changes in cpuidle.h to SWIG bindings
in cpupower (John B. Wyatt IV)

- Add output files to .gitignore and clean them up in "make clean" in
selftests/cpufreq (Li Zhijian)

- Fix cross-compilation in cpupower Makefile (Peng Fan)
