- NVIDIA Tegra audio complex, with MAX98090 CODEC
- Required properties:
- - compatible : "nvidia,tegra-audio-max98090"
- - 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 MAX98090's pins (as documented in its binding), and the jacks
- on the board:
- * Headphones
- * Speakers
- * Mic Jack
- * Int Mic
- - nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
- connected to the CODEC.
- - nvidia,audio-codec : The phandle of the MAX98090 audio codec.
- Optional properties:
- - nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in
- - nvidia,mic-det-gpios : The GPIO that detect microphones are plugged in
- Example:
- sound {
- compatible = "nvidia,tegra-audio-max98090-venice2",
- "nvidia,tegra-audio-max98090";
- nvidia,model = "NVIDIA Tegra Venice2";
- nvidia,audio-routing =
- "Headphones", "HPR",
- "Headphones", "HPL",
- "Speakers", "SPKR",
- "Speakers", "SPKL",
- "Mic Jack", "MICBIAS",
- "IN34", "Mic Jack";
- nvidia,i2s-controller = <&tegra_i2s1>;
- nvidia,audio-codec = <&acodec>;
- clocks = <&tegra_car TEGRA124_CLK_PLL_A>,
- <&tegra_car TEGRA124_CLK_PLL_A_OUT0>,
- <&tegra_car TEGRA124_CLK_EXTERN1>;
- clock-names = "pll_a", "pll_a_out0", "mclk";
- };
