It uses the DRM infrastructure to request a memory area which
the DRM variant of omapdss sends to the display hardware.
So it works with any panel setup.

Well, using an old kernel may help to get a specific version running.
We still have a 3.12 kernel for the DM3730 in our archives where the
DDK 1.9 or 1.10 works.
But our goal is to achieve something better...
With the right persistence and a lot of luck we may analyse the bugs
and what happens and find a more modern solution for all omap3.

Well, I know there are more users there than me since Philipp (@embed-3d)
created the @openpvrsgx-devgroup organization and did all the setup.
I was just invited to participate as the fifth or sixth member.
Yes, I seem to have admin rights but do not exactly know for what and
there are no collaborators and there is no team...
So maybe Philipp can manage this?

Good idea. Done.
BR and thanks,
