-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
