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
