Per the binding, this should be:
compatible = "qcom,msm8996-smmu-v2", "qcom,smmu-v2";
(note that even with Vivek's series the driver won't actually match the
SoC-specific string until we find a real need to)

And here?
Otherwise, assuming the table walk really isn't cache-coherent, and the
global and CB interrupts really do have different triggers (yuck :P),
the SMMU parts look fine to me.
