- NVIDIA Tegra audio complex
- Required properties:
- - compatible : "nvidia,tegra-audio-wm8753"
- - 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 WM8753's pins, and the jacks on the board:
- WM8753 pins:
- * LOUT1
- * LOUT2
- * ROUT1
- * ROUT2
- * MONO1
- * MONO2
- * OUT3
- * OUT4
- * LINE1
- * LINE2
- * RXP
- * RXN
- * ACIN
- * ACOP
- * MIC1N
- * MIC1
- * MIC2N
- * MIC2
- * Mic Bias
- Board connectors:
- * Headphone Jack
- * Mic Jack
- - nvidia,i2s-controller : The phandle of the Tegra I2S1 controller
- - 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";
- };
