+NVIDIA Tegra audio complex
+
+Required properties:
+- compatible : "nvidia,tegra-audio-wm9712"
+- clocks : Must contain an entry for each entry in clock-names.
+  See ../clocks/clock-bindings.txt for details.
+- clock-names : Must include the following entries:
+  - pll_a
+  - pll_a_out0
+  - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
+- nvidia,model : The user-visible name of this sound complex.
+- nvidia,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 WM9712's pins, and the jacks on the board:
+
+  WM9712 pins:
+
+  * MONOOUT
+  * HPOUTL
+  * HPOUTR
+  * LOUT2
+  * ROUT2
+  * OUT3
+  * LINEINL
+  * LINEINR
+  * PHONE
+  * PCBEEP
+  * MIC1
+  * MIC2
+  * Mic Bias
+
+  Board connectors:
+
+  * Headphone
+  * LineIn
+  * Mic
+
+- nvidia,ac97-controller : The phandle of the Tegra AC97 controller
+
+
+Example:
+
+sound {
+	compatible = "nvidia,tegra-audio-wm9712-colibri_t20",
+		         "nvidia,tegra-audio-wm9712";
+	nvidia,model = "Toradex Colibri T20";
+
+	nvidia,audio-routing =
+		"Headphone", "HPOUTL",
+		"Headphone", "HPOUTR",
+		"LineIn", "LINEINL",
+		"LineIn", "LINEINR",
+		"Mic", "MIC1";
+
+	nvidia,ac97-controller = <&ac97>;
+
+	clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>;
+	clock-names = "pll_a", "pll_a_out0", "mclk";
+};
