| Freescale i.MX audio complex with WM8960 codec |
| |
| Required properties: |
| |
| - compatible : "fsl,imx-audio-wm8960", "fsl,imx7d-evk-wm8960" |
| |
| - model : The user-visible name of this sound complex |
| |
| - cpu-dai : The phandle of CPU DAI |
| |
| - audio-codec : The phandle of the WM8960 audio codec |
| |
| - audio-routing : A list of the connections between audio components. |
| Each entry is a pair of strings, the first being the |
| connection's sink, the second being the connection's |
| source. Valid names could be power supplies, WM8960 |
| pins, and the jacks on the board: |
| |
| Power supplies: |
| * Mic Bias |
| |
| Board connectors: |
| * Mic Jack |
| * Headphone Jack |
| * Ext Spk |
| |
| Optional properties: |
| - hp-det-gpios : The gpio pin to detect plug in/out event that happens to |
| Headphone jack. |
| - mic-det-gpios: The gpio pin to detect plug in/out event that happens to |
| Microphone jack. |
| |
