Merge tag 'pm+acpi-4.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management and ACPI updates from Rafael Wysocki:
"The second batch of power management and ACPI updates for v4.6.
Included are fixups on top of the previous PM/ACPI pull request and
other material that didn't make into it but still should go into 4.6.
Among other things, there's a fix for an intel_pstate driver issue
uncovered by recent cpufreq changes, a workaround for a boot hang on
Skylake-H related to the handling of deep C-states by the platform and
a PCI/ACPI fix for the handling of IO port resources on non-x86
architectures plus some new device IDs and similar.
Specifics:
- Fix for an intel_pstate driver issue related to the handling of MSR
updates uncovered by the recent cpufreq rework (Rafael Wysocki).
- cpufreq core cleanups related to starting governors and frequency
synchronization during resume from system suspend and a locking fix
for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
- acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
Michael Neuling, Richard Cochran, Shilpasri Bhat).
- intel_idle driver update preventing some Skylake-H systems from
hanging during initialization by disabling deep C-states mishandled
by the platform in the problematic configurations (Len Brown).
- Intel Xeon Phi Processor x200 support for intel_idle
(Dasaratharaman Chandramouli).
- cpuidle menu governor updates to make it always honor PM QoS
latency constraints (and prevent C1 from being used as the fallback
C-state on x86 when they are set below its exit latency) and to
restore the previous behavior to fall back to C1 if the next timer
event is set far enough in the future that was changed in 4.4 which
led to an energy consumption regression (Rik van Riel, Rafael
Wysocki).
- New device ID for a future AMD UART controller in the ACPI driver
for AMD SoCs (Wang Hongcheng).
- Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
scaling (AVS) driver (David Wu).
- ACPI PCI resources management fix for the handling of IO space
resources on architectures where the IO space is memory mapped
(IA64 and ARM64) broken by the introduction of common ACPI
resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
- Fix for the ACPI backend of the generic device properties API to
make it parse non-device (data node only) children of an ACPI
device correctly (Irina Tirdea).
- Fixes for the handling of global suspend flags (introduced in 4.4)
during hibernation and resume from it (Lukas Wunner).
- Support for obtaining configuration information from Device Trees
in the PM clocks framework (Jon Hunter).
- ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
King, Geert Uytterhoeven)"
