+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
+
+ -- SGTL5000 pins:
+ * MIC_IN
+ * LINE_IN
+ * HP_OUT
+ * LINE_OUT
+
+ -- 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";
