Subject[PATCH v2 01/11] dt-bindings: memory: mediatek: Add mt8195 smi binding
Date
Add mt8195 smi supporting in the bindings.

In mt8195, 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 ...

MediaTek SMI have two generations of HW architecture, here is the list

There's slight differences between the two SMI, for generation 2, the
register which control the iommu port is at each larb's register base. But
