Subject - this is qcom,scm, not qcom-scm.

Which devices have interrupts?

We talked about it here:
https://lore.kernel.org/all/2464d90f-64e9-5e3c-404b-10394c3bc302@quicinc.com/
and here:
https://lore.kernel.org/all/c20edd0d-7613-5683-60e7-54317cac6e0b@linaro.org/

But I still don't get which devices support it and which do not.

Best regards,
