1 | NVIDIA Tegra audio complex, with RT5677 CODEC |
2 | ||
3 | Required properties: | |
4 | - compatible : "nvidia,tegra-audio-rt5677" | |
5 | - clocks : Must contain an entry for each entry in clock-names. | |
6 | See ../clocks/clock-bindings.txt for details. | |
7 | - clock-names : Must include the following entries: | |
8 | - pll_a | |
9 | - pll_a_out0 | |
10 | - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) | |
11 | - nvidia,model : The user-visible name of this sound complex. | |
12 | - nvidia,audio-routing : A list of the connections between audio components. | |
13 | Each entry is a pair of strings, the first being the connection's sink, | |
14 | the second being the connection's source. Valid names for sources and | |
15 | sinks are the RT5677's pins (as documented in its binding), and the jacks | |
16 | on the board: | |
17 | ||
18 | * Headphone | |
19 | * Speaker | |
20 | * Headset Mic | |
21 | * Internal Mic 1 | |
22 | * Internal Mic 2 | |
23 | ||
24 | - nvidia,i2s-controller : The phandle of the Tegra I2S controller that's | |
25 | connected to the CODEC. | |
26 | - nvidia,audio-codec : The phandle of the RT5677 audio codec. This binding | |
27 | assumes that AIF1 on the CODEC is connected to Tegra. | |
28 | ||
29 | Optional properties: | |
30 | - nvidia,hp-det-gpios : The GPIO that detects headphones are plugged in | |
31 | - nvidia,hp-en-gpios : The GPIO that enables headphone amplifier | |
32 | - nvidia,mic-present-gpios: The GPIO that mic jack is plugged in | |
33 | - nvidia,dmic-clk-en-gpios : The GPIO that gates DMIC clock signal | |
