Quick question: Does this pin description match to the board layout? I
Yes, it does.
suspect that clock and data by themselves are not enough.
They are enough as BT.656 interconnect is used between VIN1 and ADV7180.
I'm not sure about Koelsch, but in case of older SoCs using the CEU there were signals used like horizontal and vertical sync and sometimes even something that was used to determine interlace.
The HS and VS/FIELD pins of ADV7180 are left unconnected. There's also ADV7612 connected to VIN0 on this board, there the HSYNC and VSYNC/FIELD pins are connected; however, ADV7612 is not supported yet.
