1 | NVIDIA Tegra audio complex |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible : "nvidia,tegra-audio-wm8903" | |
| f9cd2b3b | 5 | - clocks : Must contain an entry for each entry in clock-names. |
| d8f64797 | 6 | See ../clocks/clock-bindings.txt for details. |
| f9cd2b3b | 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) | |
| 07cdf36d 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 | |
| d3318358 MB |
15 | sinks are the WM8903's pins (documented in the WM8903 binding document), |
| 16 | and the jacks on the board: | |

| 22 | - nvidia,i2s-controller : The phandle of the Tegra I2S1 controller | |
| 23 | - nvidia,audio-codec : The phandle of the WM8903 audio codec | |
| 24 | ||
| 25 | Optional properties: | |
| 26 | - nvidia,spkr-en-gpios : The GPIO that enables the speakers | |
| 27 | - nvidia,hp-mute-gpios : The GPIO that mutes the headphones | |
| 28 | - nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in | |
