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 && HAS_IOMEM 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.
