+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>;
