This patch adds descriptions for mt8195 IOMMU which also use ARM
Short-Descriptor translation table format.
In mt8195, 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 ...
Another change is that we have a new IOMMU that is for infra master like
PCIe and USB. The infra master don't have the larb and ports, thus we
rename the port header file to mt8195-memory-port.h rather than
mt8195-larb-port.h.
Also, the IOMMU is not only for MM, thus, we don't call it "m4u" which
means "MultiMedia Memory Management UNIT". thus, use the "iommu" as the
compatiable string.
