That's what I hoped for in the first place. But AFAICS now Rob does the splitting
of his patches himself, while the repo is used either for the
Documentation/devicetree/ patches or for the Rob'es own work. So it seems to me
I'll have to split the series up and resubmit... (

Hope I am wrong. So, @Rob, will you be able to merge this and the next two patches
in via your repo or you'd rather suggest for me to split it up and resubmit?
