It has been a while since I looked at this, but as I recall, the device 
tree bindings for keystone are horrible and make no sense. So, I made 
new bindings that make more sense. But since we can't break backwards 
compatibility in device tree, I made a new driver rather than having the 
mess of supporting two very different bindings in one driver. I don't 
know if that is a strong enough reason, but that is why I did it. :-)
