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?
