description: Everest Semiconductor ES8311 audio codec (speaker output + mic input, dual mode) include: [ "i2c-device.yaml" ] compatible: "everest,es8311" properties: i2s: type: phandle required: true description: "I2S controller device that carries audio data" input-gain-percent: type: int default: 100 description: "Extra digital gain multiplier applied by audio_stream on top of the ES8311's own 42dB hardware ADC gain, as an integer percentage (100 = 1.0x / no extra boost). For quiet MEMS mic capsules that are still quiet even at max hardware gain."
