ASoC: tegra: add tegra sgtl5000 machine driver
This binding and driver describe/support playback to headphones, and capture from line-in and microphone. This driver is useful for the Toradex Apalis T30, Apalis TK1 and Colibri T30 modules.

+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";
+};
