| 12 | description: |
| 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. |
