| Device-Tree bindings for Digital microphone (DMIC) codec |
| |
| This device support generic PDM digital microphone. |
| |
| Required properties: |
| - compatible: should be "dmic-codec". |
| |
| Optional properties: |
| - dmicen-gpios: GPIO specifier for dmic to control start and stop |
| - num-channels: Number of microphones on this DAI |
| - wakeup-delay-ms: Delay (in ms) after enabling the DMIC |
| |
| Example node: |
| |
| dmic_codec: dmic@0 { |
| compatible = "dmic-codec"; |
| dmicen-gpios = <&gpio4 3 GPIO_ACTIVE_HIGH>; |
| num-channels = <1>; |
| wakeup-delay-ms <50>; |
| }; |
