+Freescale i.MX audio complex with ES8328 codec
+
+Required properties:
+- compatible       : "fsl,imx-audio-es8328"
+- model            : The user-visible name of this sound complex
+- ssi-controller   : The phandle of the i.MX SSI controller
+- jack-gpio        : Optional GPIO for headphone jack
+- audio-amp-supply : Power regulator for speaker amps
+- audio-codec      : The phandle of the ES8328 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, ES8328
+                    pins, and the jacks on the board:
+
+                       Power supplies:
+                          * audio-amp
+
+                       ES8328 pins:
+                          * LOUT1
+                          * LOUT2
+                          * ROUT1
+                          * ROUT2
+                          * LINPUT1
+                          * LINPUT2
+                          * RINPUT1
+                          * RINPUT2
+                          * Mic PGA
+
+                       Board connectors:
+                          * Headphone
+                          * Speaker
+                          * Mic Jack
+- 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 (AUDMIX)
+
+Note: The AUDMUX port numbering should start at 1, which is consistent with
+hardware manual.
+
+Example:
+
+sound {
+       compatible = "fsl,imx-audio-es8328";
+       model = "imx-audio-es8328";

+       audio-codec = <&codec>;
+       jack-gpio = <&gpio5 15 0>;
+       audio-amp-supply = <&reg_audio_amp>;
+       audio-routing =
