1 | NVIDIA Tegra audio complex, with RT5640 CODEC |
2 | ||
3 | Required properties: | |
4 | - compatible : "nvidia,tegra-audio-rt5640" | |
5 | - clocks : Must contain an entry for each entry in clock-names. | |
d8f64797 | 6 | See ../clocks/clock-bindings.txt for details. |
040a62cf | 7 | - clock-names : Must include the following entries: |
d8f64797 SW |
8 | - pll_a |
9 | - pll_a_out0 | |
10 | - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) | |
040a62cf SW |
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 | |
b33d1f08 MB |
15 | sinks are the RT5640's pins (as documented in its binding), and the jacks |
16 | on the board: | |

21 | |
22 | - nvidia,i2s-controller : The phandle of the Tegra I2S controller that's | |
23 | connected to the CODEC. | |
24 | - nvidia,audio-codec : The phandle of the RT5640 audio codec. This binding | |
25 | assumes that AIF1 on the CODEC is connected to Tegra. | |
26 | ||
27 | Optional properties: | |
28 | - nvidia,hp-det-gpios : The GPIO that detects headphones are plugged in | |
29 | ||
