Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.19-rc1

with top-most commit 7425ecd5e3e8c9d84f399a102282a23a90a19278

 Merge branch 'pm-cpufreq'

on top of commit 9b7c19e96cededec6b0435933adefbd56cad37ab

 Merge branch 'pm-tools'

to receive the first batch of power management updates for 4.19-rc1.

These add a new framework for CPU idle time injection, to be used
by all of the idle injection code in the kernel in the future, fix
some issues and add a number of relatively small extensions in
multiple places.

Specifics:

 - Add a new framework for CPU idle time injection (Daniel Lezcano).

 - Add AVS support to the armada-37xx cpufreq driver (Gregory CLEMENT).

 - Add support for current CPU frequency reporting to the ACPI CPPC
   cpufreq driver (George Cherian).

 - Rework the cooling device registration in the imx6q/thermal
   driver (Bastian Stender).

 - Make the pcc-cpufreq driver refuse to work with dynamic
   scaling governors on systems with many CPUs to avoid
   scalability issues with it (Rafael Wysocki).

 - Fix the intel_pstate driver to report different maximum CPU
   frequencies on systems where they really are different and to
   ignore the turbo active ratio if hardware-managend P-states (HWP)
   are in use; make it use the match_string() helper (Xie Yisheng,
   Srinivas Pandruvada).

 - Fix a minor deferred probe issue in the qcom-kryo cpufreq
   driver (Niklas Cassel).

 - Add a tracepoint for the tracking of frequency limits changes
   (from Andriod) to the cpufreq core (Ruchi Kandoi).

 - Fix a circular lock dependency between CPU hotplug and sysfs
   locking in the cpufreq core reported by lockdep (Waiman Long).

 - Avoid excessive error reports on driver registration failures
   in the ARM cpuidle driver (Sudeep Holla).

 - Add a new device links flag to the driver core to make links go
   away automatically on supplier driver removal (Vivek Gautam).

 - Eliminate potential race condition between system-wide power
   management transitions and system shutdown (Pingfan Liu).

 - Add a quirk to save NVS memory on system suspend for the ASUS
   1025C laptop (Willy Tarreau).

 - Make more systems use suspend-to-idle (instead of ACPI S3) by
   default (Tristian Celestin).

 - Get rid of stack VLA usage in the low-level hibernation code on
   64-bit x86 (Kees Cook).

 - Fix error handling in the hibernation core and mark an expected
   fall-through switch in it (Chengguang Xu, Gustavo Silva).

 - Extend the generic power domains (genpd) framework to support
   attaching a device to a power domain by name (Ulf Hansson).

 - Fix device reference counting and user limits initialization in
   the devfreq core (Arvind Yadav, Matthias Kaehlcke).

 - Fix a few issues in the rk3399_dmc devfreq driver and improve its
   documentation (Enric Balletbo i Serra, Lin Huang, Nick Milner).

 - Drop a redundant error message from the exynos-ppmu devfreq driver
   (Markus Elfring).

Thanks!
