There were some minor conflicts with other patches I have in the pipe for this merge window, so this patchset is on top of what I have to avoid merge conflicts. However, the firmware patches are for code maintained by Björn. Björn, how would you like to do this? Can I take them via my tree, or what do you suggest? It's urgent to get this patchset into linux-next if it's to make it for the coming merge window. Ideally, I'd like to send my pull request to arm-soc during this week.
