| 2 | |
| 3 | Required properties: |
| 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 |
| 34 | |
| 35 | - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX) |
| 36 | |
| 37 | - mux-ext-port : The external port of the i.MX audio muxer |
| 38 | |
| 39 | Note: The AUDMUX port numbering should start at 1, which is consistent with |
| 40 | hardware manual. |
| 41 | |
| 42 | Example: |
| 43 | |
| 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>; |
| 50 | audio-routing = |
| 51 | "MIC_IN", "Mic Jack", |
| 52 | "Mic Jack", "Mic Bias", |
| 53 | "Headphone Jack", "HP_OUT"; |
| 54 | mux-int-port = <1>; |
| 55 | mux-ext-port = <3>; |
| 56 | }; |
