Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.7-rc1
with top-most commit 2409000a0cad2242fd4e2578f761f97069625478
Merge branches 'pm-devfreq', 'powercap' and 'pm-docs'
on top of commit 16fbf79b0f83bc752cee8589279f1ebfe57b3b6e
Linux 5.6-rc7
to receive power management updates for 5.7-rc1.
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).
Thanks!

These update the ACPICA code in the kernel to the 20200214 upstream
release, clean up the initialization of the EC driver, clean up the
quirk tables in the AC and battery drivers, fix the global lock
handling on x86, add a new "tiny" driver for ACPI button devices
exposed by VMs to guest kernels, modify the ACPI PCI host bridge and
fan drivers use scnprintf(), add add a kernel parameter to disable
ACPI BGRT on x86 and do some assorted cleanups.
Specifics:
- Update the ACPICA code in the kernel to the 20200214 upstream
release including:
* Fix to re-enable the sleep button after wakeup (Anchal Agarwal).
* Fixes for mistakes in comments and typos (Bob Moore).
* ASL-ASL+ converter updates (Erik Kaneda).
* Type casting cleanups (Sven Barth).
- Clean up the intialization of the EC driver and eliminate some
dead code from it (Rafael Wysocki).
- Clean up the quirk tables in the AC and battery drivers (Hans de
Goede).
- Fix the global lock handling on x86 to ignore unspecified bit
positions in the global lock field (Jan Engelhardt).
- Add a new "tiny" driver for ACPI button devices exposed by VMs to
guest kernels to send signals directly to init (Josh Triplett).
- Add a kernel parameter to disable ACPI BGRT on x86 (Alex Hung).
- Make the ACPI PCI host bridge and fan drivers use scnprintf() to
avoid potential buffer overflows (Takashi Iwai).
- Clean up assorted pieces of code:
* Reorder "asmlinkage" to make g++ happy (Alexey Dobriyan).
* Drop unneeded variable initialization (Colin Ian King).
* Add missing __acquires/__releases annotations (Jules Irenge).
* Replace list_for_each_safe() with list_for_each_entry_safe()
(chenqiwu).
Thanks!
