Whenever you introduce or modify (extend) a device tree binding please 
don't forget about reflecting that in documentation 
(Documentation/devicetree/bindings) and CCing devicetree mailing list 
(devicetree@...r.kernel.org). Both of these steps are necessary to get any 
device tree stuff merged.

Best regards,
Tomasz
