Document the Qualcomm WCD9390/WCD9395 Audio Codec and the Soundwire devices than can be found on Qualcomm SM8650 based platforms.
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.
