I only noticed today your v2. I expected a full series actually.  I am
now taking care of it. I mainly have to rename most of the commit titles
as they do not really match the subsystem where they will be applied.

I will apply all of them on the mvebu branches to avoid to more
dependency issue. However, we are very close to the end of the merge
window for arm-soc. I will do my best, but the merge of the series could
be delayed to 4.10.

Thanks,

Gregory
