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,mt2701-smi-larb"
8 "mediatek,mt2712-smi-larb"
9 "mediatek,mt6779-smi-larb"
10 "mediatek,mt7623-smi-larb", "mediatek,mt2701-smi-larb"
11 "mediatek,mt8167-smi-larb"
12 "mediatek,mt8173-smi-larb"
13 "mediatek,mt8183-smi-larb"
14 - reg : the register and size of this local arbiter.
15 - mediatek,smi : a phandle to the smi_common node.
16 - power-domains : a phandle to the power domain of this local arbiter.
17 - clocks : Must contain an entry for each entry in clock-names.
18 - clock-names: must contain 2 entries, as follows:
19 - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
21 - "smi" : It's the clock for transfer data and command.
22 and this optional clock name:
23 - "gals": the clock for GALS(Global Async Local Sync).
24 Here is the list which has this GALS: mt8183.
26 Required property for mt2701, mt2712, mt6779, mt7623 and mt8167:
