Hi Stephen,

These patches look great and I've taken them into clk-next for testing.
They should get pushed out to my Linaro mirror later today and will go
in for 3.14. Thanks for spinning the revisions to this series so
quickly.

There might still be some way to share the regmap helpers in the future,
and getting these patches merged is a good starting point.

Regards,
Mike
