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. | |
6 | - clock-names : Must include the following entries: | |
7 | "pll_a" (The Tegra clock of that name), | |
8 | "pll_a_out0" (The Tegra clock of that name), | |
9 | "mclk" (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) | |
10 | - nvidia,model : The user-visible name of this sound complex. | |
11 | - nvidia,audio-routing : A list of the connections between audio components. | |
12 | Each entry is a pair of strings, the first being the connection's sink, | |
13 | the second being the connection's source. Valid names for sources and | |
b33d1f08 MB |
14 | sinks are the RT5640's pins (as documented in its binding), and the jacks |
15 | on the board: | |

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