The Qualcomm WCD9390/WCD9395 Audio Codec communicates with the host SoC over 2 Soundwire links to provide: - 4 ADC inputs for up to 5 Analog Microphones - 4 DMIC inputs for up to 8 Digital Microphones - 4 Microphone BIAS - Stereo Headphone output - Mono EAR output - MBHC engine for Headset Detection The WCD9390/WCD9395 IC has separate I2C subsystem for USB-C DP Altmode/Audio Accessory mode Mux which is not documented here but requires port/endpoint graph and properties to handle Altmode/Audio Accessory switch and orientation.
