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)"
