| 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 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. |

| config MTK_SVS |
| bool "MediaTek Smart Voltage Scaling(SVS)" |
| depends on POWER_AVS && MTK_EFUSE |
| depends on THERMAL || THERMAL=n |
| help |
| The SVS engine is a piece of hardware which is used to calculate |
| optimized voltage values of several power domains, e.g. |
| CPU clusters/GPU/CCI, according to chip process corner, temperatures, |
| and other factors. Then DVFS driver could apply those optimized voltage |
| values to reduce power consumption. |
