Changes since v2:
 - none.
Changes since initial version:
 - dropped clocks, clock-names properties, instead properties from
   the CODEC node will be used,
 - property renames: 'samsung,model' -> 'model', 'samsung,i2s-controller'
   -> 'i2s-controller', 'samsung,speaker-amplifier' -> 'audio-amplifier',
 - added 'audio-codec' property.

+Samsung Exynos5433 TM2(E) audio complex with WM5110 codec
+
+Required properties:
+
+ - compatible : "samsung,tm2-audio"
+ - model : the user-visible name of this sound complex
+ - audio-codec: the phandle of the wm5110 audio codec node,
+   as described in Documentation/devicetree/bindings/mfd/arizona.txt
+ - i2s-controller : the phandle of the I2S controller
+ - audio-amplifier : the phandle of the MAX98504 amplifier
+ - samsung,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 for sources and sinks are the WM5110's and MAX98504's
+   pins and the jacks on the board:
+   HP, SPK, Main Mic, Sub Mic, Third Mic, Headset Mic.
+ - mic-bias-gpios : GPIO pin that enables the Main Mic bias regulator
+
+Example:
+
+sound {
+	compatible = "samsung,tm2-audio";
+	audio-codec = <&wm5110>;
+	i2s-controller = <&i2s0>;
+	audio-amplifier = <&max98504>;
+	mic-bias-gpios = <&gpr3 2 0>;
+	model = "wm5110";
+	samsung,audio-routing =
+		"HP", "HPOUT1L",
+		"HP", "HPOUT1R",
+		"SPK", "SPKOUT",
+		"SPKOUT", "HPOUT2L",
+		"SPKOUT", "HPOUT2R",
+		"Main Mic", "MICBIAS2",
+		"IN1R", "Main Mic";
+};
