usb: typec: mux: add Qualcomm WCD939X USB SubSystem Altmode Mux driver Qualcomm WCD9390/WCD9395 is a standalone Hi-Fi audio codec IC with a functionally separate USB SubSystem for Altmode/Analog Audio Switch accessible over an I2C interface. 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.

usb: typec: add support for the nb7vpq904m Type-C Linear Redriver Add support for the ON Semiconductor NB7VPQ904M Type-C USB SuperSpeed and DisplayPort ALT Mode Linear Redriver chip found on some devices with a Type-C port. The redriver compensates ultra High-Speeed DisplayPort and USB Super Speed signal integrity losses mainly due to PCB & transmission cables. The redriver doesn't support SuperSpeed lines swapping, but can support Type-C SBU lines swapping.

usb: typec: mux: Introduce GPIO-based SBU mux A design found in various Qualcomm-based boards is to use a USB switch, controlled through a pair of GPIO lines to connect, disconnect and switch the orientation of the SBU lines in USB Type-C applications. This introduces a generic driver, which implements the typec_switch and typec_mux interfaces to perform these operations.

usb: typec: mux: Add On Semi fsa4480 driver The ON Semiconductor FSA4480 is a USB Type-C port multimedia switch with support for analog audio headsets. It allows sharing a common USB Type-C port to pass USB2.0 signal, analog audio, sideband use wires and analog microphone signal. Due to lacking upstream audio support for testing, the audio muxing is left untouched, but implementation of muxing the SBU lines is provided as a pair of Type-C mux and switch devices. This provides the necessary support for enabling the DisplayPort altmode on devices with this circuit.
