Pull power management fixes from Rafael Wysocki:
"These fix issues in two cpufreq drivers, in the AMD P-state driver and
in the power-capping DTPM framework.
Specifics:
- Fix the AMD P-state driver's EPP sysfs interface in the cases when
the performance governor is in use (Ayush Jain)
- Make the ->fast_switch() callback in the AMD P-state driver return
the target frequency as expected (Gautham R. Shenoy)
- Allow user space to control the range of frequencies to use via
scaling_min_freq and scaling_max_freq when AMD P-state driver is in
use (Wyes Karny)
- Prevent power domains needed for wakeup signaling from being turned
off during system suspend on Qualcomm systems and prevent
performance states votes from runtime-suspended devices from being
lost across a system suspend-resume cycle in qcom-cpufreq-nvmem
(Stephan Gerhold)
- Fix disabling the 792 Mhz OPP in the imx6q cpufreq driver for the
i.MX6ULL types that can run at that frequency (Christoph
Niedermaier)
- Eliminate unnecessary and harmful conversions to uW from the DTPM
(dynamic thermal and power management) framework (Lukasz Luba)"
