bool "Adaptive Voltage Scaling class support"

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

Say Y here to enable support for the CPR hardware found on Qualcomm
|
|
SoCs like QCS404.
|
|
|
|
This driver populates CPU OPPs tables and makes adjustments to the
|
|
tables based on feedback from the CPR hardware. If you want to do
|
|
CPUfrequency scaling say Y here.
|
|
|
|
To compile this driver as a module, choose M here: the module will
|
|
be called qcom-cpr

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