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>;
|
|
};
