I find it's normally nicer to place the status of the node at the
bottom, separated by a '\n'. There isn't a functional difference
admittedly, but it would be my preference, since it's not describing
the device per se.

We usually use lower-case for the address.
Since this has a 'reg' property, the '0' in the node name does not
look appropriate.

Oooo, not seen something like this before.
If it does not already have one, it would require a DT Ack.

This will likely need a DT Ack too. We usually encode this sort of
information in the compatible string.

All as above.
