This patchset mainly adds SMI support for mt8192.
It comes from the patchset[1]. I seperate the smi part into this patchset.
And the two part(IOMMU/SMI) patchset don't depend on each other.
Rebase on v5.10-rc1.
changenote:
v4: add if-then segment in the binding.
v3: [1].

That would be one solution but I was thinking to proceed with only your agreement. You were the main contributor to these files. Honghui added a few descriptions. Other developers added only compatibles. Since we cannot reach Honghui, I would assume that your agreement (Sign-off) is enough.
