To avoid giving an answer that can be archived and used against me, I updated the PM branch wiki page[1] with a 'mainline plans' section[2] which I can edit as plans slip^Wchange. :) > Especially I'm interested about 2420 support for n8x0. Well, I'm afraid I've done basically no testing for OMAP2, and have been focusing solely on OMAP3. I'm pretty sure things at least should compile for OMAP2, as care has been taken to keep OMAP2 up to speed with OMAP3 for the base features, but I haven't done any boot testing on OMAP2 for some time. That being said, all the infrastructure for OMAP2 that was in linux-omap is already in mainline so will work as good as it did in linux-omap. The last time I actually tried PM on OMAP2, I found/fixed a bug[3] in the asm sleep code for OMAP2 that was causing fault. At least it no longer faults when suspended Of course, I'll be glad to take any OMAP2 patches/fixes and get them upstream with the rest of my changes, but I'm afraid with my current plans, I do not have the cycles to spend on OMAP2.
