- 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.
- - 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 RT5640's pins, and the jacks on the board:
- RT5640 pins:
- * DMIC1
- * DMIC2
- * MICBIAS1
- * IN1P
- * IN1R
- * IN2P
- * IN2R
- * HPOL
- * HPOR
- * LOUTL
- * LOUTR
- * MONOP
- * MONON
- * SPOLP
- * SPOLN
- * SPORP
- * SPORN
- Board connectors:
- * Headphones
- * Speakers
- - 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";
- };
