+Samsung Exynos Odroid XU3/XU4 audio complex with MAX98090 codec
+
+Required properties:
+
+ - compatible - "samsung,odroidxu3-audio" - for Odroid XU3 board,
+ "samsung,odroidxu4-audio" - for Odroid XU4 board
+ - model - the user-visible name of this sound complex
+ - 'cpu' subnode with a 'sound-dai' property containing the phandle of the I2S
+ controller
+ - 'codec' subnode with a 'sound-dai' property containing list of phandles
+ to the CODEC nodes, first entry must be corresponding to the MAX98090
+ CODEC and the second entry must be the phandle of the HDMI IP block node
+ - clocks - should contain entries matching clock names in the clock-names
+ property
+ - clock-names - should contain following entries:
+ - "epll" - indicating the EPLL output clock
+ - "i2s_rclk" - indicating the RCLK (root) clock of the I2S0 controller
+ - samsung,audio-widgets - this property specifies off-codec audio elements
+ like headphones or speakers, for details see widgets.txt
+ - 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 MAX98090's pins (as
+ documented in its binding), and the jacks on the board
+
+ For Odroid X2:
+ "Headphone Jack", "Mic Jack", "DMIC"
+
+ For Odroid U3, XU3:
+ "Headphone Jack", "Speakers"
+
+ For Odroid XU4:
+ no entries
+
+Example:
+
+sound {
+ compatible = "samsung,odroidxu3-audio";
+ samsung,cpu-dai = <&i2s0>;
+ samsung,codec-dai = <&max98090>;
+ model = "Odroid-XU3";
+ samsung,audio-routing =
+ "Headphone Jack", "HPL",
+ "Headphone Jack", "HPR",
+ "IN1", "Mic Jack",
+ "Mic Jack", "MICBIAS";
+
+ clocks = <&clock CLK_FOUT_EPLL>, <&i2s0 CLK_I2S_RCLK_SRC>;
+ clock-names = "epll", "sclk_i2s";
+
+ cpu {
+ sound-dai = <&i2s0 0>;
+ };
+ codec {
+ sound-dai = <&hdmi>, <&max98090>;
+ };
+};
