All of the separate bits can be merged separately without problems, so Lee can take the 2 mfd patches, you can take the power-supply patch and Mark Brown can take the regulator patch. I believe that that is the best merge strategy.

Thanks, any chance we can see this show up soonish in : https://git.kernel.org/cgit/linux/kernel/git/lee/mfd.git/log/?h=for-mfd-next ? We keep a branch with all the foo-for-next branches relevant for sunxi merged in for testing and it would be good to get these in there.
