How does it work? From what I can tell from the information I find when googling this part[1] and looking at the existing binding doc is that this device is a DPI to DP bridge, and it outputs DP (probably 4 lanes of it?). Does the 2 type-c port design work by transmitting DP on two lanes of DP for one type-c port and another two lanes of DP for the other type-c port?
DP could be one lane, so if this device is able to output one lane on any output differential pair then I suspect it could support 4 type-c ports if the hardware engineer connected it that way. Can you confirm my suspicion?
