Merge tag 'pm-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These add support for new processors (Sierra Forest, Grand Ridge and
Meteor Lake) to the intel_idle driver, make intel_pstate run on
Emerald Rapids without HWP support and adjust it to utilize EPP values
supplied by the platform firmware, fix issues, clean up code and
improve documentation.

The most significant fix addresses deadlocks in the core system-wide
resume code that occur if async_schedule_dev() attempts to run its
argument function synchronously (for example, due to a memory
allocation failure). It rearranges the code in question which may
increase the system resume time in some cases, but this basically is a
removal of a premature optimization. That optimization will be added
back later, but properly this time.

Specifics:

- Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)

- Do not enable interrupts when entering idle in the haltpoll cpuidle
driver (Borislav Petkov)

- Add Emerald Rapids support in no-HWP mode to the intel_pstate
cpufreq driver (Zhenguo Yao)

- Use EPP values programmed by the platform firmware as balanced
performance ones by default in intel_pstate (Srinivas Pandruvada)

- Add a missing function return value check to the SCMI cpufreq
driver to avoid unexpected behavior (Alexandra Diupina)

- Fix parameter type warning in the armada-8k cpufreq driver (Gregory
CLEMENT)

- Rework trans_stat_show() in the devfreq core code to avoid buffer
overflows (Christian Marangi)

- Synchronize devfreq_monitor_[start/stop] so as to prevent a timer
list corruption from occurring when devfreq governors are switched
frequently (Mukesh Ojha)

- Fix possible deadlocks in the core system-wide PM code that occur
if device-handling functions cannot be executed asynchronously
during resume from system-wide suspend (Rafael J. Wysocki)

- Clean up unnecessary local variable initializations in multiple
places in the hibernation code (Wang chaodong, Li zeming)

- Adjust core hibernation code to avoid missing wakeup events that
occur after saving an image to persistent storage (Chris Feng)

- Update hibernation code to enforce correct ordering during image
compression and decompression (Hongchen Zhang)

- Use kmap_local_page() instead of kmap_atomic() in copy_data_page()
during hibernation and restore (Chen Haonan)

- Adjust documentation and code comments to reflect recent tasks
freezer changes (Kevin Hao)

- Repair excess function parameter description warning in the
hibernation image-saving code (Randy Dunlap)

- Fix _set_required_opps when opp is NULL (Bryan O'Donoghue)

- Use device_get_match_data() in the OPP code for TI (Rob Herring)

- Clean up OPP level and other parts and call dev_pm_opp_set_opp()
recursively for required OPPs (Viresh Kumar)"

ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.
