Yeah, this should have been done from the beginning, when the driver has been
re-used for Keystone, but this time is already missed, so I don't want
to introduce huge incompatibility with the existing device-trees.

And from the other PoV, device-trees are for something one cannot probe. We
can probe for Keystone revisions and can free the end-user from this headache
completely.
