   6 Required properties:
   7 - compatible: "fsl,imx35-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 a
  10   pin working on a specific function, CONFIG is the pad setting value like
  11   pull-up for this pin. Please refer to imx35 datasheet for the valid pad
  12   config settings.
