good you mention it. I added Grant on Cc and will give a short
sum-up why I casted the const from property->value away here.

Maybe I overlooked the API for modifying the DT property but as
far as I've seen - there is no API for modifying it. And yes,
you are right, it is kind of an abuse of DT here.

Sparc has an of_set_property(), it needs to become generic.
