Hi Joerg,
     Sorry for reply late.
     The ARM short descriptor is independent. This one can be merged
independently.

     But the mtk-iommu depend on the drivers/memory/mtk-smi.c(mtk-iommu
has called a function of the mtk-smi).
     So if there is dependence here, How should we do to merge them?
