* Audio codec controlled by ChromeOS EC



Google's ChromeOS EC codec is a digital mic codec provided by the

Embedded Controller (EC) and is controlled via a host-command interface.



An EC codec node should only be found as a sub-node of the EC node (see

Documentation/devicetree/bindings/mfd/cros-ec.txt).



Required properties:

- compatible: Must contain "google,cros-ec-codec"

- #sound-dai-cells: Should be 1. The cell specifies number of DAIs.

- max-dmic-gain: A number for maximum gain in dB on digital microphone.



Example:



cros-ec@0 {

	compatible = "google,cros-ec-spi";



	...



	cros_ec_codec: ec-codec {

		compatible = "google,cros-ec-codec";

		#sound-dai-cells = <1>;

		max-dmic-gain = <43>;

	};

};
