7 title: Qualcomm WCD9380/WCD9385 USB SubSystem Altmode/Analog Audio Switch
10   - Neil Armstrong <neil.armstrong@linaro.org>
13   Qualcomm WCD9390/WCD9395 is a standalone Hi-Fi audio codec IC with a
14   functionally separate USB SubSystem for Altmode/Analog Audio Switch
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
