The stuff you write here will be forever imprinted in the git history
and it's already unnecessary, given that the patch you reference here is
available in linux-next.

Things you want to mention, but shouldn't go into the git history, put
those below the '---' line.

I do however now see this compatible defined in a binding in linux-next,
so you definitely should have listed that patch as a dependency - and
preferably held off sending me 6 versions (plus resend) of a patch that
I can't merge.

Please ping me once the binding is merged, so that I know when I can
merge this patch.

Thanks,
Bjorn
