This series introduces a level of indirection between the controller's view of a typec_mux/switch and the implementation and then expands that to support multiple drivers. This is needed in order to support devices such as the Qualcomm Snapdragon 888 HDK, which does muxing and orientation handling in the QMP (USB+DP) PHY and SBU muxing in the external FSA4480 chip.
