| 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"; |
| }; |
