+NVIDIA Tegra audio complex, with SGTL5000 CODEC
+
+Required properties:
+- compatible : "nvidia,tegra-audio-sgtl5000"
+- 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 SGTL5000's pins (as documented in its binding), and the jacks
+  on the board:
+
+  * Headphone Jack
+  * Line In Jack
+  * Mic Jack
+
+- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
+  connected to the CODEC.
+- nvidia,audio-codec : The phandle of the SGTL5000 audio codec.
+
+Example:
+
+sound {
+	compatible = "toradex,tegra-audio-sgtl5000-apalis_t30",
+		     "nvidia,tegra-audio-sgtl5000";
+	nvidia,model = "Toradex Apalis T30";
+	nvidia,audio-routing =
+		"Headphone Jack", "HP_OUT",
+		"LINE_IN", "Line In Jack",
+		"MIC_IN", "Mic Jack";
+	nvidia,i2s-controller = <&tegra_i2s2>;
+	nvidia,audio-codec = <&sgtl5000>;
+	clocks = <&tegra_car TEGRA30_CLK_PLL_A>,
+		 <&tegra_car TEGRA30_CLK_PLL_A_OUT0>,
+		 <&tegra_car TEGRA30_CLK_EXTERN1>;
+	clock-names = "pll_a", "pll_a_out0", "mclk";
