menuconfig POWER_AVS
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.
config QCOM_CPR
tristate "QCOM Core Power Reduction (CPR) support"
depends on POWER_AVS
select PM_OPP
select REGMAP
help
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
config ROCKCHIP_IODOMAIN
tristate "Rockchip IO domain support"
depends on POWER_AVS && ARCH_ROCKCHIP && OF
help
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.
