| * 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>; |
| }; |
| }; |
