+Freescale VF610 audio complex with SGTL5000 codec
+
+Required properties:
+- compatible: "fsl,vf610-sgtl5000"
+- model: The user-visible name of this sound complex.
+- saif-controllers: The phandle list of the SAI controller.
+- audio-codec: The phandle of the SGTL5000 audio codec.
+- audio-routing : A list of the connections between audio components.
+  Each entry is a pair of strings, the first being the connection's sink,
+  the second being the connection's source. Valid names could be power
+  supplies, SGTL5000 pins, and the jacks on the board:
+
+  -- Power supplies:
+     * Mic Bias
+
+  -- Board connectors:
+     * Mic Jack
+     * Line In Jack
+     * Headphone Jack
+     * Line Out Jack
+     * Ext Spk
+
+Example:
+
+sound {
+	compatible = "fsl,vf610-sgtl5000";
+	model = "vf610-sgtl5000";
+	saif-controller = <&sai2>;
+	audio-codec = <&codec>;
+	audio-routing =
+		"MIC_IN", "Mic Jack",
+		"Mic Jack", "Mic Bias",
+		"LINE_IN", "Line In Jack",
+		"Headphone Jack", "HP_OUT",
+		"Ext Spk", "LINE_OUT";
+};
+
+&i2c0 {
+	...
+
+	codec: sgtl5000@0a {
+	       compatible = "fsl,sgtl5000";
+	       reg = <0x0a>;
+	       clocks = <&clks VF610_CLK_SAI2>;
+       };
+};
