NVIDIA Tegra audio complex



Required properties:

- compatible : "nvidia,tegra-audio-alc5632"

- 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



  Board connectors:



  * Headset Stereophone

  * Int Spk

  * Headset 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>;
