| 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";
| };
