   6Required properties:
   7- compatible: "fsl,vf610-iomuxc"
   8- fsl,pins: two integers array, represents a group of pins mux and config
   9  setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is
  10  a pin working on a specific function, CONFIG is the pad setting value
  11  such as pull-up, speed, ode for this pin. Please refer to Vybrid VF610
  12  datasheet for the valid pad config settings.
