1 | NVIDIA Tegra audio complex, with SGTL5000 CODEC |
2 | ||
3 | Required properties: | |
4 | - compatible : "nvidia,tegra-audio-sgtl5000" | |
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 SGTL5000's pins (as documented in its binding), and the jacks | |
16 | on the board: | |
17 | ||
18 | * Headphone Jack | |
19 | * Line In Jack | |
20 | * Mic Jack | |
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 SGTL5000 audio codec. | |
25 | ||
26 | Example: | |
27 | ||
28 | sound { | |
29 | compatible = "toradex,tegra-audio-sgtl5000-apalis_t30", | |
30 | "nvidia,tegra-audio-sgtl5000"; | |
31 | nvidia,model = "Toradex Apalis T30"; | |
32 | nvidia,audio-routing = | |
33 | "Headphone Jack", "HP_OUT", | |
34 | "LINE_IN", "Line In Jack", | |
35 | "MIC_IN", "Mic Jack"; | |
36 | nvidia,i2s-controller = <&tegra_i2s2>; | |
37 | nvidia,audio-codec = <&sgtl5000>; | |
38 | clocks = <&tegra_car TEGRA30_CLK_PLL_A>, | |
39 | <&tegra_car TEGRA30_CLK_PLL_A_OUT0>, | |
40 | <&tegra_car TEGRA30_CLK_EXTERN1>; | |
41 | clock-names = "pll_a", "pll_a_out0", "mclk"; | |
42 | }; |
