[GIT PULL] Power management updates for v7.1-rc1

["Rafael J. Wysocki" <rafael@kernel.org>]

Hi Linus,

This goes early because I will be traveling next week.

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-7.1-rc1

with top-most commit d923f70e37310fe613883a3a4c2ea2f31246253b

 Merge branch 'pm-devfreq'

on top of commit 591cd656a1bf5ea94a222af5ef2ee76df029c1d2

 Linux 7.0-rc7

to receive power management updates for 7.1-rc1.

Once again, cpufreq is the most active development area, mostly because
of the new feature additions and documentation updates in the amd-pstate
driver, but there are also changes in the cpufreq core related to boost
support and other assorted updates elsewhere.

Next up are power capping changes due to the major cleanup of the Intel
RAPL driver.

On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.

Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates
of the operating performance points (OPP) library, two minor updates
related to hibernation, and cpupower utility man pages updates and
cleanups.

Specifics:

 - Update qcom-hw DT bindings to include Eliza hardware (Abel Vesa)

 - Update cpufreq-dt-platdev blocklist (Faruque Ansari)

 - Minor updates to driver and dt-bindings for Tegra (Thierry Reding,
   Rosen Penev)

 - Add MAINTAINERS entry for CPPC driver (Viresh Kumar)

 - Add support for new features: CPPC performance priority, Dynamic EPP,
   Raw EPP, and new unit tests for them to amd-pstate (Gautham Shenoy,
   Mario Limonciello)

 - Fix sysfs files being present when HW missing and broken/outdated
   documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)

 - Pass the policy to cpufreq_driver->adjust_perf() to avoid using
   cpufreq_cpu_get() in the .adjust_perf() callback in amd-pstate which
   leads to a scheduling-while-atomic bug (K Prateek Nayak)

 - Clean up dead code in Kconfig for cpufreq (Julian Braha)

 - Remove max_freq_req update for pre-existing cpufreq policy and add a
   boost_freq_req QoS request to save the boost constraint instead of
   overwriting the last scaling_max_freq constraint (Pierre Gondois)

 - Embed cpufreq QoS freq_req objects in cpufreq policy so they all
   are allocated in one go along with the policy to simplify lifetime
   rules and avoid error handling issues (Viresh Kumar)

 - Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
   scaling driver (Henry Tseng)

 - Switch policy_is_shared() in cpufreq to using cpumask_nth() instead
   of cpumask_weight() because the former is more efficient (Yury Norov)

 - Use sysfs_emit() in sysfs show functions for cpufreq governor
   attributes (Thorsten Blum)

 - Update intel_pstate to stop returning an error when "off" is written
   to its status sysfs attribute while the driver is already off (Fabio
   De Francesco)

 - Include current frequency in the debug message printed by
   __cpufreq_driver_target() (Pengjie Zhang)

 - Refine stopped tick handling in the menu cpuidle governor and
   rearrange stopped tick handling in the teo cpuidle governor (Rafael
   Wysocki)

 - Add Panther Lake C-states table to the intel_idle driver (Artem
   Bityutskiy)

 - Clean up dead dependencies on CPU_IDLE in Kconfig (Julian Braha)

 - Simplify cpuidle_register_device() with guard() (Huisong Li)

 - Use performance level if available to distinguish between rates in
   OPP debugfs (Manivannan Sadhasivam)

 - Fix scoped_guard in dev_pm_opp_xlate_required_opp() (Viresh Kumar)

 - Return -ENODATA if the snapshot image is not loaded (Alberto Garcia)

 - Remove inclusion of crypto/hash.h from hibernate_64.c on x86 (Eric
   Biggers)

 - Clean up and rearrange the intel_rapl power capping driver to make
   the respective interface drivers (TPMI, MSR, and MMOI) hold their
   own settings and primitives and consolidate PL4 and PMU support
   flags into rapl_defaults (Kuppuswamy Sathyanarayanan)

 - Correct kernel-doc function parameter names in the power capping core
   code (Randy Dunlap)

 - Remove unneeded casting for HZ_PER_KHZ in devfreq (Andy Shevchenko)

 - Use _visible attribute to replace create/remove_sysfs_files() in
   devfreq (Pengjie Zhang)

 - Add Tegra114 support to activity monitor device in tegra30-devfreq as
   a preparation to upcoming EMC controller support (Svyatoslav Ryhel)

 - Fix mistakes in cpupower man pages, add the boost and epp options to
   the cpupower-frequency-info man page, and add the perf-bias option to
   the cpupower-info man page (Roberto Ricci)

 - Remove unnecessary extern declarations from getopt.h in arguments
   parsing functions in cpufreq-set, cpuidle-info, cpuidle-set,
   cpupower-info, and cpupower-set utilities (Kaushlendra Kumar)

Thanks!
