1 | NVIDIA Tegra audio complex |
2 | ||
3 | Required properties: | |
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: | |
