To my mind I need some kind of assurance from the clk maintainers that the
patches are stable there - in particular that the commit ids won't change.
And that both they and the ARM-SoC maintainers are happy with me pulling
it into my tree for this purpose.

I do wonder, as we are almost at the closing point for queuing up changes
for v4.7 if, assuming the above patches are scheduled for inclusion in
v4.7-rc1, it might not be better for me to queue up this series for v4.8.

I could do that sooner rather than later in the devel branch of the renesas
tree if you like.
