+# ES8311 audio codec
+
+A driver for the `ES8311` audio codec by Everest Semiconductor, wired as a dual
+in/out `AUDIO_CODEC_TYPE` device (speaker output + microphone input on the same
+chip). The I2C bus is the device's parent; the I2S controller carrying audio data
+is referenced via a devicetree phandle.
+
+Wraps Espressif's `esp_codec_dev` ES8311 implementation.
