Hi Philipp, yes currently the crtc's are fixed to a DI. I wasn't aware that
there are future plans to change this.

But I don't see any difference between the crtcs being created in code versus
in the device tree, even with the above new info. In both cases, the assigned
DI could simply be an initial assignment that can be re-assigned on mode changes.
