Needless to say I am very happy about this patch series which fixes
some stuff that has been causing pain and frustration for ages and
then improves on top of that.
Acked-by: Linus Walleij <linus.walleij at linaro.org>
for the series.

I would really like to sit down and read it line-by-line, look at
macros etc and find any minor corner issues, but I am unable
to at this point (time). I am sure I can find and fix any issues on
my pet systems if any arise, and it overall looks very good.

Yours,
Linus Walleij
