    1 NVIDIA Tegra audio complex, with MAX98090 CODEC
    2 
    3 Required properties:
    4 - compatible : "nvidia,tegra-audio-max98090"
    5 - clocks : Must contain an entry for each entry in clock-names.
    6   See ../clocks/clock-bindings.txt for details.
    7 - clock-names : Must include the following entries:
    8   - pll_a
    9   - pll_a_out0
   10   - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
   11 - nvidia,model : The user-visible name of this sound complex.
   12 - nvidia,audio-routing : A list of the connections between audio components.
   13   Each entry is a pair of strings, the first being the connection's sink,
   14   the second being the connection's source. Valid names for sources and
   15   sinks are the MAX98090's pins (as documented in its binding), and the jacks
   16   on the board:
   17 
   18   * Headphones
   19   * Speakers
   20   * Mic Jack
   21   * Int Mic
   22 
   23 - nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
   24   connected to the CODEC.
   25 - nvidia,audio-codec : The phandle of the MAX98090 audio codec.
   26 
   27 Optional properties:
   28 - nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in
   29 - nvidia,mic-det-gpios : The GPIO that detect microphones are plugged in
   30 
   31 Example:
   32

   36         nvidia,model = "NVIDIA Tegra Venice2";
   37 
   38         nvidia,audio-routing =

   44                 "IN34", "Mic Jack";
   45 
   46         nvidia,i2s-controller = <&tegra_i2s1>;
   47         nvidia,audio-codec = <&acodec>;
   48
