| SMI (Smart Multimedia Interface) Local Arbiter |
| |
| The hardware block diagram please check bindings/iommu/mediatek,iommu.txt |
| |
| Required properties: |
| - compatible : must be one of : |
| "mediatek,mt2701-smi-larb" |
| "mediatek,mt2712-smi-larb" |
| "mediatek,mt8173-smi-larb" |
| - reg : the register and size of this local arbiter. |
| - mediatek,smi : a phandle to the smi_common node. |
| - power-domains : a phandle to the power domain of this local arbiter. |
| - clocks : Must contain an entry for each entry in clock-names. |
| - clock-names: must contain 2 entries, as follows: |
| - "apb" : Advanced Peripheral Bus clock, It's the clock for setting |
| the register. |
| - "smi" : It's the clock for transfer data and command. |
| |
| Required property for mt2701 and mt2712: |
| - mediatek,larb-id :the hardware id of this larb. |
