I'd strongly recommend that you also pass the configuration explicitly
here, so as to avoid nasty surprises. For that you can either use a path
or an alias, depending on what the rest of your DT looks like:

	stdout-path = "/path/to/scifa0:115200n8"

	stdout-path = "serial0:115200n8"

Thanks,
Mark.
