13   Qualcomm WCD9390/WCD9395 Codec is a standalone Hi-Fi audio codec IC.
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
19   to handle USB-C altmode & orientation switching for Audio Accessory Mode.
