Okay. I think that resolves the last open issue. I'll try to get some
more work done on the DT and corresponding code soonish.

For those who don't know yet I've requested the creation of a project
on freedesktop.org for Tegra graphics drivers[0]. I plan to have the DRM
code hosted there once the project has been approved. Furthermore if we
ever get to write a corresponding X driver it can be hosted there as
well. We should also use the wiki for coordination once things get
started.
