1	* Freescale IMX35 IOMUX Controller
2	
3	Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
4	and usage.
5	
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.
