Ah, right, I forgot that I actually fixed dt-schema:
It seems like we can cope with "clocks" being just a node name in
schema/clock/clock.yaml [1], but not in meta-schemas/clocks.yaml [2].
I added a similar anyOf ... to the meta-schemas entry, which seems to
fix it for me.
Can you confirm that this is a bug in dt-schema and this is the proper
fix or am I doing something wrong (I have only a smattering in
dt-schema/json)?
Cheers,
Andre
