That makes sense to me now. 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.
