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



Example node:



	dmic_codec: dmic@0 {

		compatible = "dmic-codec";

		dmicen-gpios = <&gpio4 3 GPIO_ACTIVE_HIGH>;

	};

RT274 audio CODEC



This device supports I2C only.



Required properties:



- compatible : "realtek,rt274".



- reg : The I2C address of the device.



Optional properties:



- interrupts : The CODEC's interrupt output.





Pins on the device (for linking into audio routes) for RT274:



  * DMIC1 Pin

  * DMIC2 Pin

  * MIC

  * LINE1

  * LINE2

  * HPO Pin

  * SPDIF

  * LINE3



Example:



codec: rt274@1c {

	compatible = "realtek,rt274";

	reg = <0x1c>;

	interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
