+NVIDIA Tegra audio complex, with RT5677 CODEC
+
+Required properties:
+- compatible : "nvidia,tegra-audio-rt5677"
+- 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 RT5677's pins (as documented in its binding), and the jacks
+  on the board:
+
+  * Headphone
+  * Speaker
+  * Headset Mic
+  * Internal Mic 1
+  * Internal Mic 2
+
+- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
+  connected to the CODEC.
+- nvidia,audio-codec : The phandle of the RT5677 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
+- nvidia,hp-en-gpios : The GPIO that enables headphone amplifier
+- nvidia,mic-present-gpios: The GPIO that mic jack is plugged in
+- nvidia,dmic-clk-en-gpios : The GPIO that gates DMIC clock signal
+

+
