+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
+
+Example:
+
