Right, it should be -dais.

The "qcom,q6asm" is handled in:
Documentation/devicetree/bindings/soc/qcom/qcom,apr.yaml

The "qcom,q6asm-v<MAJOR-NUMBER>.<MINOR-NUMBER>" is not handled because
it seems it is not used anywhere. I did not find such usage also in
downstream sources, so it seems version can be always auto-detected (I
did not confirm it with datasheet, though).

I'll explain this in commit msg.

Best regards,
