description: |
Qualcomm WCD9390/WCD9395 Codec is a standalone Hi-Fi audio codec IC.
It has RX and TX Soundwire devices.
The WCD9390/WCD9395 IC has a functionally separate USB-C Mux subsystem
accessible over an I2C interface.
The Audio Headphone and Microphone data path between the Codec and the USB-C Mux
subsystems are external to the IC, thus requiring DT port-endpoint graph description
to handle USB-C altmode & orientation switching for Audio Accessory Mode.
