NVIDIA Tegra audio complex

Required properties:
- compatible : "nvidia,tegra-audio-alc5632"
- clocks : Must contain an entry for each entry in clock-names.
- clock-names : Must include the following entries:
  "pll_a" (The Tegra clock of that name),
  "pll_a_out0" (The Tegra clock of that name),
  "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 ALC5632's pins:

  ALC5632 pins:

  * SPK_OUTP
  * SPK_OUTN
  * HP_OUT_L
  * HP_OUT_R
  * AUX_OUT_P
  * AUX_OUT_N
  * LINE_IN_L
  * LINE_IN_R
  * PHONE_P
  * PHONE_N
  * MIC1_P
  * MIC1_N
  * MIC2_P
  * MIC2_N
  * MICBIAS1
  * DMICDAT

  Board connectors:

  * Headset Stereophone
  * Int Spk
  * Headset Mic
  * Digital Mic

- nvidia,i2s-controller : The phandle of the Tegra I2S controller
- nvidia,audio-codec : The phandle of the ALC5632 audio codec

Example:

sound {
	compatible = "nvidia,tegra-audio-alc5632-paz00",
				 "nvidia,tegra-audio-alc5632";

	nvidia,model = "Compal PAZ00";

	nvidia,audio-routing =
				"Int Spk", "SPK_OUTP",
				"Int Spk", "SPK_OUTN",
				"Headset Mic","MICBIAS1",
				"MIC1_N", "Headset Mic",
				"MIC1_P", "Headset Mic",
				"Headset Stereophone", "HP_OUT_R",
				"Headset Stereophone", "HP_OUT_L";

	nvidia,i2s-controller = <&tegra_i2s1>;
	nvidia,audio-codec = <&alc5632>;

	clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>;
	clock-names = "pll_a", "pll_a_out0", "mclk";
};
