| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "nvidia,tegra-audio-alc5632" |
| 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 ALC5632's pins as documented in the binding for the device |
| 16 | and: |
| 17 | |
| 18 | * Headset Stereophone |
| 19 | * Int Spk |
| 20 | * Headset Mic |
| 21 | * Digital Mic |
| 22 | |
| 23 | - nvidia,i2s-controller : The phandle of the Tegra I2S controller |
| 24 | - nvidia,audio-codec : The phandle of the ALC5632 audio codec |
| 25 | |
| 26 | Example: |
