If you use clock-names, please define the clocks property in terms of clock-names to avoid redundancy. e.g. - clocks: a list of phandles + clock-specifiers, one for each entry in clock-names. It makes the relationship between the two clearer, and makes it far easier to alter the binding in future if required.
