Read the feedback there:
"So, as you are submitting the first node(s) under network_bus: bus@5, you
should have this added into your patchset, instead of sending out with
none."
Plus simple bus within MMIO node needs unit address. IOW, don't mix MMIO
with non-MMIO. I also suspect this does not pass checks, so the tools
can do our review...
Best regards,
Krzysztof
