3 bool "Adaptive Voltage Scaling class support"
5 AVS is a power management technique which finely controls the
6 operating voltage of a device in order to optimize (i.e. reduce)
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.
13 Say Y here to enable Adaptive Voltage Scaling class support.
15 config ROCKCHIP_IODOMAIN
16 tristate "Rockchip IO domain support"
17 depends on POWER_AVS && ARCH_ROCKCHIP && OF
19 Say y here to enable support io domains on Rockchip SoCs. It is
20 necessary for the io domain setting of the SoC to match the
21 voltage supplied by the regulators.
