Hi Gregory

That is a good question, but i've no knowledge in this area.

Rafa??, what is the long term plan? Will the device specific property
be removed sometime in the future, and nor-jedec probing be used to
identify the device? Is this already the actual behaviour?  I've seen
warnings when the DT entry specified the wrong device, something like:
Found ABC, Expected XYZ.
