And endpoint must have a 'remote-endpoint' property, and the endpoint on the other end must have similar property, pointing in the first endpoint. Anything else is an error. I agree that it's easier to write bad links in the dts with double-linking than with single-linking, but it's still trivial to verify it in the kernel. Tomi
