+* Freescale IMX6 SoloLite IOMUX Controller
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
+and usage.
+
+Required properties:
+- compatible: "fsl,imx6sl-iomuxc"
+- fsl,pins: two integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+ pin working on a specific function, CONFIG is the pad setting value like
+ pull-up for this pin. Please refer to imx6sl datasheet for the valid pad
+ config settings.
