| 2 | ||
| 3 | Required properties: | |
| afa1fde6 NC |
4 | |
| 5 | - compatible : "fsl,imx-audio-sgtl5000" | |
| 6 | ||
| 7 | - model : The user-visible name of this sound complex | |
| 8 | ||
| 9 | - ssi-controller : The phandle of the i.MX SSI controller | |
| 10 | ||
| 11 | - audio-codec : The phandle of the SGTL5000 audio codec | |
| 12 | ||
| 13 | - audio-routing : A list of the connections between audio components. | |
| 14 | Each entry is a pair of strings, the first being the | |
| 15 | connection's sink, the second being the connection's | |
| 16 | source. Valid names could be power supplies, SGTL5000 | |
| 17 | pins, and the jacks on the board: | |
| 18 | ||
| 19 | Power supplies: | |
| 20 | * Mic Bias | |
| 21 | ||
| 22 | SGTL5000 pins: | |
| 23 | * MIC_IN | |
| 24 | * LINE_IN | |
| 25 | * HP_OUT | |
| 26 | * LINE_OUT | |
| 27 | ||
| 28 | Board connectors: | |
| 29 | * Mic Jack | |
| 30 | * Line In Jack | |
| 31 | * Headphone Jack | |
| 32 | * Line Out Jack | |
| 33 | * Ext Spk | |

| 44 | sound { | |
| 45 | compatible = "fsl,imx51-babbage-sgtl5000", | |
| 46 | "fsl,imx-audio-sgtl5000"; | |
| 47 | model = "imx51-babbage-sgtl5000"; | |
| 48 | ssi-controller = <&ssi1>; | |
| 49 | audio-codec = <&sgtl5000>; | |
| 172b4c5c | 50 | audio-routing = |
| 065899c9 | 51 | "MIC_IN", "Mic Jack", |
| 172b4c5c | 52 | "Mic Jack", "Mic Bias", |
| 172b4c5c | 53 | "Headphone Jack", "HP_OUT"; |
