| Nicolin Chen | 6a6dec8 | 2014-10-07 12:29:11 -0700 | [diff] [blame] | 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 |

| 31 | Note: The AUDMUX port numbering should start at 1, which is consistent with |
| 32 | hardware manual. |
