Would be good to have a small amount of description here + it seems you didn't
sign off on this patch so we can't apply it to the kernel.

Please cc devicetree list and maintainers for any devicetree bindings.
+cc Rob, Mark and list.

Thanks,

Not sure why you need the pre colon bit here.

Also I'd imagine the standard naming for a dac is probably
dac@0
(I haven't checked the devicetree spec to see if they actually
have that one in there as I'm on a train with dodgy wifi).
