Its etm0700g0dh6 vs. et070080dh6, Philipp's panel is with captive multi
touch, (hence the M I guess). The panel itself really looks the same.

I found this overview of EDT displays:
http://www.dmbtechnics.com/scripts/passthru.php?id=7

There seem to be quite a lot variants with the same panel...

Regarding timings, I just checked the documentation, Philipp's timing
really matches the documented ones, I miscalculated the vertical back
porch.

How do we resolve that?

I would suggest that I split out that patch and remove the et070080dh6
panel and send the other as a single patch to the dri-devel mailing list
as well.

Philipp, could you add my display type (et070080dh6) to the compatible
list of your mode/panel entry?

Does this sound reasonable?
