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. Included in the series is a the new FSA4480 driver. This is done to deal with the renaming of the driver-side typec_mux -> typec_mux_dev. Changes since v1: - Omitted QMP changes from this series, as the muxing implementation needs a little bit more debugging.
