1 * Freescale IMX6 DualLite/Solo IOMUX Controller
3 Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
7 - compatible: "fsl,imx6dl-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 imx6dl datasheet for the valid pad
