Okay, so that means that the panel works for you with the same timings that Philipp has in the ETM0700G0DH6 patch? If so then I definitely think we should be sharing the timings in the driver by making the two compatible entries point to the same driver data. > 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. Yes, that would work. > Philipp, could you add my display type (et070080dh6) to the compatible > list of your mode/panel entry? I also noticed that Philipp's patch doesn't actually introduce the device tree bindings, so that will have to be added as well.
