It is expected that all future platforms will use the generic qcom,smmu-500 compat string in addition to SoC-specific and the generic arm,mmu-500 ones. Older bindings are now described as deprecated. Note: I have split the sdx55 and sdx65 from the legacy bindings. They are not supported by the qcom SMMU implementation. I can suppose that they are using the generic implementation rather than the Qualcomm-speicific one.
