This series already reviewed in public more than six months. In the
early version, 8173 CCF and Pinctrl not be accepted yet, so we don't put
device node with this series. Now both CCF and pinctrl have been
accepted, maybe it's time to add device node.I am glad that if this I2C
version can be accepted, If not, I will send new series with device node
in next round.

I think this is good to go. Further changes should probably done as
incremental patches. I am just waiting a little so people can add tags
to the patches.
