 | 	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. |

 |         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. |
