1 SMI (Smart Multimedia Interface) Local Arbiter
3 The hardware block diagram please check bindings/iommu/mediatek,iommu.txt
6 - compatible : must be one of :
7 "mediatek,mt8173-smi-larb"
8 "mediatek,mt2701-smi-larb"
9 - reg : the register and size of this local arbiter.
10 - mediatek,smi : a phandle to the smi_common node.
11 - power-domains : a phandle to the power domain of this local arbiter.
12 - clocks : Must contain an entry for each entry in clock-names.
13 - clock-names: must contain 2 entries, as follows:
14 - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
