Then I am not sure if we want to support such devices mainline. It is
not only anonymity but simply not following standards and practices.
What's more there is no guarantee what this device is. If there is no
known manufacturer, anytime another device from anyone can claim it is
also uf896. IOW, what guarantees you have that other person who has
something looking like "uf896" actually has something the same as you
and can use your DTB?

I don't know how to reasonably support entirely unknown devices.
