Well, this has been discussed almost to death already (as you may
remember ;-) in the thread:

http://www.spinics.net/lists/devicetree/msg00072.html

(only portions survived)

Although I was in favour of the generic binding (as were you if I
remember correctly), the final non-conclusion was not to open the
"generic door". Fair enough with me, I went the defined-in-code way
here...
