As discussed elsewhere, there are four additional keys on the
Landingship (you proposed as sub-node names key1-key4).
I prefer preparing the label now over adding it in a later patch.

The other RK3368 boards don't, so unless you can give a justification to
convert all boards yet again and test how this makes a difference, I'd
rather not do experiments here but leave that to someone who knows what
they're doing and then do it consistently...
Thanks for the detailed review,
