Having a required root node compatible is fine, though I would only expect it to be necessary for errata workarounds if we have no other way of detecting things. That said, compatible strings shouldn't have wildcards, so "cavium,thunder-88xx" should be replaced with something more specific. Later boards can claim compatibility with that (but should have their own strings too).
