6*21e59123SShawn GuoRequired properties:
7*21e59123SShawn Guo- compatible: "fsl,imx6sl-iomuxc"
8*21e59123SShawn Guo- fsl,pins: two integers array, represents a group of pins mux and config
9*21e59123SShawn Guo  setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
10*21e59123SShawn Guo  pin working on a specific function, CONFIG is the pad setting value like
11*21e59123SShawn Guo  pull-up for this pin. Please refer to imx6sl datasheet for the valid pad
12*21e59123SShawn Guo  config settings.
