| NVIDIA Tegra audio complex, with RT5640 CODEC
|
| Required properties:
| - compatible : "nvidia,tegra-audio-rt5640"
| - 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 RT5640's pins (as documented in its binding), and the jacks
| on the board:
|
| * Headphones
| * Speakers
| * Mic Jack
|
| - nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
| connected to the CODEC.
| - nvidia,audio-codec : The phandle of the RT5640 audio codec. This binding
| assumes that AIF1 on the CODEC is connected to Tegra.
|
| Optional properties:
| - nvidia,hp-det-gpios : The GPIO that detects headphones are plugged in
|
| Example:
|
| sound {
| compatible = "nvidia,tegra-audio-rt5640-dalmore",
| "nvidia,tegra-audio-rt5640";
| nvidia,model = "NVIDIA Tegra Dalmore";
|
| nvidia,audio-routing =
| "Headphones", "HPOR",
| "Headphones", "HPOL",
| "Speakers", "SPORP",
| "Speakers", "SPORN",
| "Speakers", "SPOLP",
| "Speakers", "SPOLN";
|
| nvidia,i2s-controller = <&tegra_i2s1>;
| nvidia,audio-codec = <&rt5640>;
|
| nvidia,hp-det-gpios = <&gpio 143 0>; /* GPIO PR7 */
|
| clocks = <&tegra_car 216>, <&tegra_car 217>, <&tegra_car 120>;
| clock-names = "pll_a", "pll_a_out0", "mclk";
| };
