The M4U-SMI HW diagram is as below: EMI | M4U | ------------ SMI Common ------------ | +-------+------+------+----------------------+-------+ | | | | ...... | | | | | | | | larb0 larb1 larb2 larb4 ...... larb19 larb20 disp0 disp1 mdp vdec IPE IPE All the connections are HW fixed, SW can NOT adjust it. Comparing with the preview SoC, this patchset also adds two functions: a) add iova 34 bits support. b) add multi domains support since several HW has the special iova region requirement. this patchset depend on v5.8-rc1 and mt6779 iommu[1].
