| 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 | }; |
