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.

+Required properties:
+
+ - compatible : "samsung,tm2-audio"

+ - 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:

+ - 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",
