It provides switching USB-C USB2.0 lines between USB and Audio Headphones speaker lines, and the USB-C SBU lines between DisplayPort AUX and Audio Headphones Microphone/Ground. 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.
