1 NVIDIA Tegra audio complex
4 - compatible : "nvidia,tegra-audio-wm8903"
5 - nvidia,model : The user-visible name of this sound complex.
6 - nvidia,audio-routing : A list of the connections between audio components.
7 Each entry is a pair of strings, the first being the connection's sink,
8 the second being the connection's source. Valid names for sources and
9 sinks are the WM8903's pins, and the jacks on the board:
36 - nvidia,i2s-controller : The phandle of the Tegra I2S1 controller
37 - nvidia,audio-codec : The phandle of the WM8903 audio codec
40 - nvidia,spkr-en-gpios : The GPIO that enables the speakers
41 - nvidia,hp-mute-gpios : The GPIO that mutes the headphones
42 - nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in
43 - nvidia,int-mic-en-gpios : The GPIO that enables the internal microphone
44 - nvidia,ext-mic-en-gpios : The GPIO that enables the external microphone
