   4         help
   5           AVS is a power management technique which finely controls the
   6           operating voltage of a device in order to optimize (i.e. reduce)
   7           its power consumption.
   8           At a given operating point the voltage is adapted depending on
   9           static factors (chip manufacturing process) and dynamic factors
  10           (temperature depending performance).
  11           AVS is also called SmartReflex on OMAP devices.
  12
  13           Say Y here to enable Adaptive Voltage Scaling class support.

  21           Say Y here to enable support for the CPR hardware found on Qualcomm
  22           SoCs like QCS404.
  23
  24           This driver populates CPU OPPs tables and makes adjustments to the
  25           tables based on feedback from the CPR hardware. If you want to do
  26           CPUfrequency scaling say Y here.

  28           To compile this driver as a module, choose M here: the module will
  29           be called qcom-cpr

  35           Say y here to enable support io domains on Rockchip SoCs. It is
  36           necessary for the io domain setting of the SoC to match the
  37           voltage supplied by the regulators.
