I have proposed this before, but I'll do it again: I'm more than happy to be the official person who collects and organizes the omap and davinci patches for you and who does the initial reviews. This is effectively already the case since I've been reviewing both omap and davinci patches pretty much from the beginning. Both the omap2/3 display driver and the davinci drivers are now very close to be ready for inclusion in the kernel as my last reviews only found some minor things. Part of the reason for the delays for both omap and davinci was that they had to be modified for v4l2_subdev, which was an absolute necessity, and because they simply needed quite a bit of work to make them suitable for inclusion in the kernel.
