| description: | |
| Qualcomm WCD9390/WCD9395 Codec is a standalone Hi-Fi audio codec IC. |
| It has RX and TX Soundwire devices. |
| The WCD9390/WCD9395 IC has a functionally separate USB-C Mux subsystem |
| accessible over an I2C interface. |
| The Audio Headphone and Microphone data path between the Codec and the USB-C Mux |
| subsystems are external to the IC, thus requiring DT port-endpoint graph description |
| to handle USB-C altmode & orientation switching for Audio Accessory Mode. |
