          two integers array, represents a group of pins mux and config setting.
          The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a pin
          working on a specific function, CONFIG is the pad setting value such
          as pull-up, speed, ode for this pin. Please refer to Vybrid VF610
          datasheet for the valid pad config settings.
