+Required properties:
+ - compatible : "samsung,odroidx2-audio" - for Odroid X2 board,
+		"samsung,odroidu3-audio" - for Odroid U3 board
+ - samsung,model : the user-visible name of this sound complex
+ - samsung,i2s-controller : the phandle of the I2S controller
+ - samsung,audio-codec : the phandle of the MAX98090 audio codec
+ - samsung,audio-routing : a list of the connections between audio

+   For Odroid X2:
+     * Headphone Jack
+     * Mic Jack
+     * DMIC
+
+   For Odroid U3:
