This may be a bit premature if you are not providing a binding document
for this sub-node, you might as well add it once you also add a
corresponding driver (or if this will remain out of tree, at least
submitting a separate binding document).

Also, if this node's unit address is 0, you would expect at least a reg
property whose address cell is 0 to be present.
