12description:
13  Qualcomm WCD9390/WCD9395 is a standalone Hi-Fi audio codec IC with a
14  functionally separate USB SubSystem for Altmode/Analog Audio Switch
15  accessible over an I2C interface.
16  The Audio Headphone and Microphone data path between the Codec and the
17  USB-C Mux subsystems are external to the IC, thus requiring DT port-endpoint
18  graph description to handle USB-C altmode & orientation switching for Audio
19  Accessory Mode.
