Heh, I suggested something similar in my reply to Kalle. Let's go with
'qcom,ath11k-pci.yaml' then as he first suggested (and keeping the
current schema file unchanged?).

This one is already in use as you noticed.

Yeah, I was actively avoiding trying to say too much (e.g. mentioning
the name of the current firmware file). See the definition in
qcom,ath11k.yaml.

I can try to find some middle ground unless you prefer copying the
current definition.
