Subject: [GIT PULL] Power management updates for v5.1-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.1-rc1

with top-most commit 1271d6d576b7e7c80519de211f250cfd4eebca1a

 Merge branch 'pm-opp'

on top of commit 5b317cbf2bcb85a1e96ce87717cb991ecab1dd4d

 Merge branch 'pm-cpufreq-fixes'

to receive power management updates for 5.1-rc1.

These are PM-runtime framework changes to use ktime instead of
jiffies for accounting, new PM core flag to mark devices that don't
need any form of power management, cpuidle updates including driver
API documentation and a new governor, cpufreq updates including a new
driver for Armada 8K, thermal cleanups and more, some energy-aware
scheduling (EAS) enabling changes, new chips support in the intel_idle
and RAPL drivers and assorted cleanups in some other places.

Specifics:

 - Update the PM-runtime framework to use ktime instead of
   jiffies for accounting (Thara Gopinath, Vincent Guittot).

 - Optimize the autosuspend code in the PM-runtime framework
   somewhat (Ladislav Michl).

 - Add a PM core flag to mark devices that don't need any form of
   power management (Sudeep Holla).

 - Introduce driver API documentation for cpuidle and add a new
   cpuidle governor for tickless systems (Rafael Wysocki).

 - Add Jacobsville support to the intel_idle driver (Zhang Rui).

 - Clean up a cpuidle core header file and the cpuidle-dt and ACPI
   processor-idle drivers (Yangtao Li, Joseph Lo, Yazen Ghannam).

 - Add new cpufreq driver for Armada 8K (Gregory Clement).

 - Fix and clean up cpufreq core (Rafael Wysocki, Viresh Kumar,
   Amit Kucheria).

 - Add support for light-weight tear-down and bring-up of CPUs to the
   cpufreq core and use it in the cpufreq-dt driver (Viresh Kumar).

 - Fix cpu_cooling Kconfig dependencies, add support for CPU cooling
   auto-registration to the cpufreq core and use it in multiple
   cpufreq drivers (Amit Kucheria).

 - Fix some minor issues and do some cleanups in the davinci,
   e_powersaver, ap806, s5pv210, qcom and kryo cpufreq drivers
   (Bartosz Golaszewski, Gustavo Silva, Julia Lawall, Paweł Chmiel,
   Taniya Das, Viresh Kumar).

 - Add a Hisilicon CPPC quirk to the cppc_cpufreq driver (Xiongfeng
   Wang).

 - Clean up the intel_pstate and acpi-cpufreq drivers (Erwan Velu,
   Rafael Wysocki).

 - Clean up multiple cpufreq drivers (Yangtao Li).

 - Update cpufreq-related MAINTAINERS entries (Baruch Siach, Lukas
   Bulwahn).

 - Add support for exposing the Energy Model via debugfs and make
   multiple cpufreq drivers register an Energy Model to support
   energy-aware scheduling (Quentin Perret, Dietmar Eggemann,
   Matthias Kaehlcke).

 - Add Ice Lake mobile and Jacobsville support to the Intel RAPL
   power-capping driver (Gayatri Kammela, Zhang Rui).

 - Add a power estimation helper to the operating performance points
   (OPP) framework and clean up a core function in it (Quentin Perret,
   Viresh Kumar).

 - Make minor improvements in the generic power domains (genpd), OPP
   and system suspend frameworks and in the PM core (Aditya Pakki,
   Douglas Anderson, Greg Kroah-Hartman, Rafael Wysocki, Yangtao Li).

Thanks!
