Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.
Specifics:
- Operating Performance Points (OPP) framework fixes, cleanups and
switch over from RCU-based synchronization to reference counting
using krefs (Viresh Kumar, Wei Yongjun, Dave Gerlach)
- cpufreq core cleanups and documentation updates (Viresh Kumar,
Rafael Wysocki)
- New cpufreq driver for Broadcom BMIPS SoCs (Markus Mayer)
- New cpufreq-dt sub-driver for TI SoCs requiring special handling,
like in the AM335x, AM437x, DRA7x, and AM57x families, along with
new DT bindings for it (Dave Gerlach, Paul Gortmaker)
- ARM64 SoCs support for the qoriq cpufreq driver (Tang Yuantian)
- intel_pstate driver updates including a new sysfs knob to control
the driver's operation mode and fixes related to the no_turbo sysfs
knob and the hardware-managed P-states feature support (Rafael
Wysocki, Srinivas Pandruvada)
- New interface to export ultra-turbo frequencies for the powernv
cpufreq driver (Shilpasri Bhat)
- Assorted fixes for cpufreq drivers (Arnd Bergmann, Dan Carpenter,
Wei Yongjun)
- devfreq core fixes, mostly related to the sysfs interface exported
by it (Chanwoo Choi, Chris Diamand)
- Updates of the exynos-bus and exynos-ppmu devfreq drivers (Chanwoo
Choi)
- Device PM QoS extension to support CPUs and support for per-CPU
wakeup (device resume) latency constraints in the cpuidle menu
governor (Alex Shi)
- Wakeup IRQs framework fixes (Grygorii Strashko)
- Generic power domains framework update including a fix to make it
handle asynchronous invocations of *noirq suspend/resume callbacks
correctly (Ulf Hansson, Geert Uytterhoeven)
- Assorted fixes and cleanups in the core suspend/hibernate code, PM
QoS framework and x86 ACPI idle support code (Corentin Labbe, Geert
Uytterhoeven, Geliang Tang, John Keeping, Nick Desaulniers)
- Update of the analyze_suspend.py script is updated to version 4.5
offering multiple improvements (Todd Brandt)
- New tool for intel_pstate diagnostics using the pstate_sample
tracepoint (Doug Smythies)"
