Just to let you know that I plan to apply the 3 arm patch once Chris
will have sent the new series with the minor fixes I asked on patch 3.
I already applied them in the for-next branch to benefit of some build
test coverage.
Stephen,
you gave your Acked-by on the first patch, but don't you plan to apply
it on the clk branch?
If you really want I can apply on mvebu but there is no build
dependencies, so the order the patches will be merged is not important.
Linus,
I expect you will apply the pinctrl patch on your tree as it depend of
code already there.
Thanks,
Gregory
