CM3 touch screen compatibility

Hey all!

I’m currently working on getting my CM3 running on my Bigtreetech Manta M8P board. The core features are working, but DSI for example not. I haven’t found a dtb which was designed explicitely for the CM3 and a CM4 IO board. When I tried to use the Rock 3C dtb for the Raspberry 7 inch touch, the CM3 wasn’t even able to boot anymore.

Has anybody successfully got it working on the CM3?
