They are indeed quite similar, but there are a few diffs, especially 
after fixing Laurent's review comments.

E.g, as the UB913 is a parallel video serializer and the UB953 is a 
CSI-2 serializer, the input port on UB913 has 'pclk-sample' property but 
UB953 has 'data-lanes' property. The descriptions differ also a bit for 
the above mentioned difference.

The above points would still allow combining the bindings, though. But I 
feel the UB913 is somewhat a different class of serializer device 
compared to UB953 (and UB971 which the UB953's binding also supports), 
so my gut feeling says it's better to keep them separate. But I don't 
have much experience on maintaining such bindings, and, afaik, we could 
always split the bindings later if needed.

So... Do you have a preference on either way? Or maybe we can come back 
to this after I send the next version with the updates.

Ok.
