This patch adds description for MT6779 IOMMU. MT6779 has two iommus, they are mm_iommu and apu_iommu which both use ARM Short-Descriptor translation format. In addition, mm_iommu and apu_iommu are two independent HW instance , we need to set them separately. The MT6779 IOMMU hardware diagram is as below, it is only a brief diagram about iommu, it don't focus on the part of smi_larb, so I don't describe the smi_larb detailedly. EMI | -------------------------------------- | | MM_IOMMU APU_IOMMU | | SMI_COMMOM----------- APU_BUS | | | SMI_LARB(0~11) | | | | | | | -------------- | | | | | Multimedia engine CCU VPU MDLA EMDA All the connections are hardware fixed, software can not adjust it.
