Add documentation for Chrome EC codec driver.
Signed-off-by: Cheng-Yi Chiang cychiang@chromium.org
Change in v4:

+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>;};+}; diff --git a/MAINTAINERS b/MAINTAINERS index 4d04cebb4a71..a5678e4041e9 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3688,6 +3688,13 @@ N: cros_ec N: cros-ec F: drivers/power/supply/cros_usbpd-charger.c
