I've seen new properties many times added, even though the new driver wouldn't work quite right on old DT files. I've also seen people create a new hardware compatibility name for a totally new binding. Finally, I've seen the bindings just randomly change for no reason with no concern for backwards compat. The last really sucks if you have a driver that's not in the Linux tree (say, because it's a FreeBSD driver).
