13 Qualcomm WCD9390/WCD9395 Codec is a standalone Hi-Fi audio codec IC.
14 It has RX and TX Soundwire devices.
15 The WCD9390/WCD9395 IC has a functionally separate USB-C Mux subsystem
17 The Audio Headphone and Microphone data path between the Codec and the USB-C Mux
18 subsystems are external to the IC, thus requiring DT port-endpoint graph description
