OK, let's plan on merging these then. Want me to pick these, or pull from some branch? Looks like they also need to be posted to LAKML too, and we should get them into linux-omap master for some testing. Looks like these should not cause much of merge issues with the gpio platform init patches. It would be nice to get those merged too if possible.
