Uh? Why would we ever care about decompiling some DTBs?

I don't understand your arguments. Schema expects this to have proper
name (see bindings). DT spec as well.

I have no clue what you are testing here. We do not care about some out
of tree DTB. And if you ask about upstream, then take conversions tasks
after reading this:

BTW, your patch has patch errors which *have to be fixed* as well. Apply
your patch to see them. Run checkpatch.
