IIUC the built-in mux in anx7625 is designed for automatically switching between two orientations of a single Type-C connector, and in that case we might need to register an orientation switch. But we don't have hardware for this use case. The use case this series aimed is having two downstreams for the bridges, and registering two mode switches to switch between them. In this use case, the built-in mux of anx7625 is not used and the behavior of the switches is the same as it6505. Explanations and TODOs have been added in the anx7625 driver change. I can also mention this in the cover letter in the future series and please let me know if anything is not clear for you. > > Rob Thanks and regards, Pin-yen
