Ok, just to be sure I understand the process here. I should resend a new
version of the whole patchset including the devicetree mailing list as
recipent. Then the first 3 patches will eventually get pushed by a clock
subsystem maintainer. And finally this last patch will be pushed by a
devicetree maintainer.

Am I right here ?
