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
|
||
|
|
|
||
|
