Real users with mainline kernel with a real product should always have priority over any ongoing clean-up. And for testing, a bunch of real users is something you can't beat for proper testing of code on ongoing basis! Naturally the burden of getting the patches ready is on the people using them for rebase and fixing comments. And Sebastian has already agreed help with maintaining it. I've been actually using DSI command mode support and testing Linux next several times a week to prevent regressions from sneaking into -rc1 in general. So now I can't test omapdrm with next until Sebastian is done with rebasing.. Back to headless testing then. Anyways, I'd say let's add the DSI command mode support ASAP after rebasing, there are at least Sebastian, Pavel and I then testing and helping with further ongoing panel conversion work.
