+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";
+};
