-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";
-};
