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.
