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

   6Required 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.
