NVIDIA Tegra audio complex
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-wm8753"
|
|
- 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 WM8753's pins as documented in the binding for the WM8753,
|
|
and the jacks on the board:
|
|
|
|
* Headphone Jack
|
|
* Mic Jack

|
|
- nvidia,audio-codec : The phandle of the WM8753 audio codec
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "nvidia,tegra-audio-wm8753-whistler",
|
|
"nvidia,tegra-audio-wm8753"
|
|
nvidia,model = "tegra-wm8753-harmony";
|
|
|
|
nvidia,audio-routing =
|
|
"Headphone Jack", "LOUT1",
|
|
"Headphone Jack", "ROUT1";
|
|
|
|
nvidia,i2s-controller = <&i2s1>;
|
|
nvidia,audio-codec = <&wm8753>;
|
|
|
|
clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>;
|
|
clock-names = "pll_a", "pll_a_out0", "mclk";
|
|
};
