Add descriptions for mt8188 IOMMU which also use ARM Short-Descriptor
translation table format.
In mt8188, there are two smi-common HW and IOMMU, one is for vdo(video
output), the other is for vpp(video processing pipe). They connects
with different smi-larbs, then some setting(larbid_remap) is different.
Differentiate them with the compatible string.
Something like this:
IOMMU(VDO) IOMMU(VPP)
| |
SMI_COMMON_VDO SMI_COMMON_VPP
--------------- ----------------
| | ... | | ...
larb0 larb2 ... larb1 larb3 ...
We also have an IOMMU that is for infra master like PCIe.
And infra master don't have the larb and ports.
