| 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 |
| 16 | accessible over an I2C interface. |
| 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. |
