| 4 | AVS is a power management technique which finely controls the |
| 5 | operating voltage of a device in order to optimize (i.e. reduce) |
| 6 | its power consumption. |
| 7 | At a given operating point the voltage is adapted depending on |
| 8 | static factors (chip manufacturing process) and dynamic factors |
| 9 | (temperature depending performance). |
| 10 | AVS is also called SmartReflex on OMAP devices. |

| 12 | Say Y here to enable Adaptive Voltage Scaling class support. |

| 18 | Say y here to enable support io domains on Rockchip SoCs. It is |
| 19 | necessary for the io domain setting of the SoC to match the |
| 20 | voltage supplied by the regulators. |
