    3 Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
    4 and usage.

    6 Required properties:
    7 - compatible: "fsl,imx51-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 imx51 datasheet for the valid pad
   12   config settings.
