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 first entry should be phandle of the wm5110 audio

			   codec node, as described in ../mfd/arizona.txt;

			   the second entry should be phandle of the HDMI

			   transmitter node

 - i2s-controller	 : the list of phandle and argument tuples pointing to

			   I2S controllers, the first entry should be I2S0 and

			   the second one I2S1

 - 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>, <&hdmi>;

	i2s-controller = <&i2s0 0>, <&i2s1 0>;

	audio-amplifier = <&max98504>;

	mic-bias-gpios = <&gpr3 2 0>;

	model = "wm5110";

	samsung,audio-routing =

		"HP", "HPOUT1L",

		"HP", "HPOUT1R",

		"SPKOUT", "HPOUT2L",

		"SPKOUT", "HPOUT2R",

		"Main Mic", "MICBIAS2",

		"IN1R", "Main Mic";
