+Freescale i.MX audio complex with SGTL5000 codec
+
+Required properties:
+
+  - compatible		: "fsl,imx-audio-sgtl5000"
+
+  - model		: The user-visible name of this sound complex
+
+  - ssi-controller	: The phandle of the i.MX SSI 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
+
+  - mux-int-port	: The internal port of the i.MX audio muxer (AUDMUX)
+
+  - mux-ext-port	: The external port of the i.MX audio muxer
+
+Note: The AUDMUX port numbering should start at 1, which is consistent with
+hardware manual.
+
+Example:
+
+sound {
+	compatible = "fsl,imx51-babbage-sgtl5000",
+		     "fsl,imx-audio-sgtl5000";
+	model = "imx51-babbage-sgtl5000";
+	ssi-controller = <&ssi1>;
+	audio-codec = <&sgtl5000>;
+	audio-routing =
+		"MIC_IN", "Mic Jack",
+		"Mic Jack", "Mic Bias",
+		"Headphone Jack", "HP_OUT";
+	mux-int-port = <1>;
+	mux-ext-port = <3>;
+};
