The tidss_kms.c associates a DSS VP and a DT port, but that's no longer true if you add the ports for both OLDI TXes, as they both use the same VP. I think fixing that won't affect this patch, though, and merging this patch will, afaik, enable similar DSS functionality as we have for AM65x. So, I think these two patches could be merged, or we could wait a bit until the OLDI situation becomes more clear. Up to you. In any case, for both patches: Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Tomi

This patch set is required for the dss DT patches to be upstreamed for the AM625-SK, so I would like them to get merged.

I'd like to understand better the dual OLDI TX case before merging any AM625 dss changes. At the moment you have only one port in the DT for the OLDI TX for AM625, right? I don't see how that is supposed to work as there are two OLDI outputs. And if we do add a new port, it perhaps makes sense to have two OLDI TX ports as ports 0 and 1, and the DPI as port 2, which is then different from AM65x. Tomi

The DSS still has a single (DPI) VP for the OLDI outputs. Both the OLDI TXes receive the same input from the DSS VP. Wouldn't having them modeled as videp ports 0 and 1 would mean that the DSS is capable of driving 2 different OLDI displays? (which is not the case here). Regards Aradhya

If you use the OLDI cloning, the AM625 is driving two OLDI displays, no? In theory the panels could be of different model, as long as they both support the same video mode, and they could be managed by different drivers. This requires two ports so that you can connect the panels in the DT. But let's continue this discussion in the "[PATCH 4/8] drm/tidss: Add support for Dual Link LVDS Bus Format" thread, no need to discuss the same things in two threads =). Tomi
