Merge tag 'pm-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
"These clean up and rework the PM QoS API, address a suspend-to-idle
wakeup regression on some ACPI-based platforms, clean up and extend a
few cpuidle drivers, update multiple cpufreq drivers and cpufreq
documentation, and fix a number of issues in devfreq and several other
things all over.
Specifics:
- Clean up and rework the PM QoS API to simplify the code and reduce
the size of it (Rafael Wysocki).
- Fix a suspend-to-idle wakeup regression on Dell XPS13 9370 and
similar platforms where the USB plug/unplug events are handled by
the EC (Rafael Wysocki).
- CLean up the intel_idle and PSCI cpuidle drivers (Rafael Wysocki,
Ulf Hansson).
- Extend the haltpoll cpuidle driver so that it can be forced to run
on some systems where it refused to load (Maciej Szmigiero).
- Convert several cpufreq documents to the .rst format and move the
legacy driver documentation into one common file (Mauro Carvalho
Chehab, Rafael Wysocki).
- Update several cpufreq drivers:
* Extend and fix the imx-cpufreq-dt driver (Anson Huang).
* Improve the -EPROBE_DEFER handling and fix unwanted CPU
overclocking on i.MX6ULL in imx6q-cpufreq (Anson Huang,
Christoph Niedermaier).
* Add support for Krait based SoCs to the qcom driver (Ansuel
Smith).
* Add support for OPP_PLUS to ti-cpufreq (Lokesh Vutla).
* Add platform specific intermediate callbacks support to
cpufreq-dt and update the imx6q driver (Peng Fan).
* Simplify and consolidate some pieces of the intel_pstate
driver and update its documentation (Rafael Wysocki, Alex
Hung).
- Fix several devfreq issues:
* Remove unneeded extern keyword from a devfreq header file and
use the DEVFREQ_GOV_UPDATE_INTERNAL event name instead of
DEVFREQ_GOV_INTERNAL (Chanwoo Choi).
* Fix the handling of dev_pm_qos_remove_request() result
(Leonard Crestez).
* Use constant name for userspace governor (Pierre Kuo).
* Get rid of doc warnings and fix a typo (Christophe JAILLET).
- Use built-in RCU list checking in some places in the PM core to
avoid false-positive RCU usage warnings (Madhuparna Bhowmik).
- Add explicit READ_ONCE()/WRITE_ONCE() annotations to low-level PM
QoS routines (Qian Cai).
- Fix removal of wakeup sources to avoid NULL pointer dereferences in
a corner case (Neeraj Upadhyay).
- Clean up the handling of hibernate compat ioctls and fix the
related documentation (Eric Biggers).
- Update the idle_inject power capping driver to use variable-length
arrays instead of zero-length arrays (Gustavo Silva).
- Fix list format in a PM QoS document (Randy Dunlap).
- Make the cpufreq stats module use scnprintf() to avoid potential
buffer overflows (Takashi Iwai).
- Add pm_runtime_get_if_active() to PM-runtime API (Sakari Ailus).
- Allow no domain-idle-states DT property in generic PM domains (Ulf
Hansson).
- Fix a broken y-axis scale in the intel_pstate_tracer utility (Doug
Smythies)"
