The OF graph needs to be updated to accurately show the data flow. 2. The tidss and OLDI drivers now need to support the dual-link and the cloned single-link OLDI video signals. 3. The drivers also need to support the case where 2 OLDI TXes are connected to 2 different VPs - thereby creating 2 independent streams of single-link OLDI outputs.Have you considered/tested the use case in which only single link is used? You do not mention it here and to me this is a relevant use case. There is a workaround for this (use option 2, cloned, even if nothing is connected to the second link), but this seems not correct. We (Max in Cc here) noticed that this specific use case is broken on your downstream v6.6 TI branch.
What if you set "fw_devlink=off" kernel boot parameter? Tomi
