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.
BTW: https://lore.kernel.org/all/20221122092345.44369-2-krzysztof.kozlowski@linaro.org/
Best regards, Krzysztof
