6Required properties:
7- compatible: "fsl,imx50-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 imx50 datasheet for the valid pad
12  config settings.
