Merge tag 'pm-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These rework cpuidle governors to call tick_nohz_get_sleep_length()
less often and fix one of them, rework hibernation to avoid storing
pages filled with zeros in hibernation images, switch over some
cpufreq drivers to use void remove callbacks, fix and clean up
multiple cpufreq drivers, fix the devfreq core, update the cpupower
utility and make other assorted improvements.

Specifics:

- Rework the menu and teo cpuidle governors to avoid calling
tick_nohz_get_sleep_length(), which is likely to become quite
expensive going forward, too often and improve making decisions
regarding whether or not to stop the scheduler tick in the teo
governor (Rafael Wysocki)

cases (Liao Chang)

cpufreq_verify_within_limits() (Liao Chang)

callback (Yangtao Li)

- Add online/offline/exit hooks for Tegra driver (Sumit Gupta)

- Explicitly include correct DT includes in cpufreq (Rob Herring)

- Frequency domain updates for qcom-hw driver (Neil Armstrong)

- Modify AMD pstate driver return the highest_perf value (Meng Li)

- Generic cleanups for cppc, mediatek and powernow driver (Liao
Chang, Konrad Dybcio)

- Add more platforms to cpufreq-arm driver's blocklist
(AngeloGioacchino Del Regno and Konrad Dybcio)

- brcmstb-avs-cpufreq: Fix -Warray-bounds bug (Gustavo A. R. Silva)

- Add device PM helpers to allow a device to remain powered-on during
system-wide transitions (Ulf Hansson)

- Rework hibernation memory snapshotting to avoid storing pages
filled with zeros in hibernation image files (Brian Geffon)

- Add check to make sure that CPU latency QoS constraints do not use
negative values (Clive Lin)

- Optimize rp->domains memory allocation in the Intel RAPL power
capping driver (xiongxin)

- Remove recursion while parsing zones in the arm_scmi power capping
driver (Cristian Marussi)

- Fix memory leak in devfreq_dev_release() (Boris Brezillon)

- Rewrite devfreq_monitor_start() kerneldoc comment (Manivannan
Sadhasivam)

- Explicitly include correct DT includes in devfreq (Rob Herring)

- Remove unsued pm_runtime_update_max_time_suspended() extern
declaration (YueHaibing)

- Add turbo-boost support to cpupower (Wyes Karny)

- Add support for amd_pstate mode change to cpupower (Wyes Karny)

- Fix 'cpupower idle_set' command to accept only numeric values of
arguments (Likhitha Korrapati)

- Clean up OPP code and add new frequency related APIs to it (Viresh
Kumar, Manivannan Sadhasivam)

- Convert ti cpufreq/opp bindings to json schema (Nishanth Menon)"

cpuidle: menu: Skip tick_nohz_get_sleep_length() call in some cases

Because the cost of calling tick_nohz_get_sleep_length() may increase
in the future, reorder the code in menu_select() so it first uses the
statistics to determine the expected idle duration. If that value is
higher than RESIDENCY_THRESHOLD_NS, tick_nohz_get_sleep_length() will
be called to obtain the time till the closest timer and refine the
idle duration prediction if necessary.

This causes the governor to always take the full overhead of
get_typical_interval() with the assumption that the cost will be
amortized by skipping the tick_nohz_get_sleep_length() call in the
cases when the predicted idle duration is relatively very small.
