HiSIlicon hip06/07 boards have a similar existing option to enable, ARM_SMMU_OPT_SKIP_PREFETCH. I have just sent out a similar patch to enable It-" [PATCH] iommu/arm-smmu-v3: Enable ACPI based HiSilicon CMD_PREFETCH quirk(erratum 161010701)". May be it can be merged here, if this series goes through. Not sure about the protocol though.
I think you can add a patch on top of Geetha's, and clarify the dependency in the change log, then it will be easy for maintainer to apply.
