Agree, I noticed the same things.

Alos, the compatible string should be:

compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";

(note the order reversal, most specific is first)

and I think it is better to use the 'data' field of of_device_id than
a of_is_compatible call. The former is sensitive to order of the
compatible string, the latter is not.
