1 | Freescale i.MX audio complex with WM8962 codec |
| 2 | ||
| 3 | Required properties: | |
| 6a6dec83 NC |
4 | |
| 5 | - compatible : "fsl,imx-audio-wm8962" | |
| 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 WM8962 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, WM8962 | |
| 17 | pins, and the jacks on the board: | |
| 18 | ||
| 19 | Power supplies: | |
| 20 | * Mic Bias | |
| 21 | ||
| 22 | Board connectors: | |
| 23 | * Mic Jack | |
| 24 | * Headphone Jack | |
| 25 | * Ext Spk | |
| 26 | ||
| 27 | - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX) | |
| 28 | ||
| 29 | - mux-ext-port : The external port of the i.MX audio muxer | |
