| 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 |
| - codec-enable-gpio : The GPIO used to enable the audio codec |
| |
