I looked through the code and i don't see anything obviously
wrong. But so long as we get the ABI correct, we can fix everything
else later. And the ABI here is just the device tree binding. And that
is identical to the i2c binding. The properties just go in a different
place in the tree. So please do the *TODO*, you can look at other
examples, e.g. the Marvell binding documentation.

With that done, i will ACK this code.
