+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 ../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";
+};
