In mt8188, there are two smi-common HW, one is for vdo(video output), the other is for vpp(video processing pipe). They connect with different smi-larbs, then some setting(bus_sel) 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 ...
