1 | SMI (Smart Multimedia Interface) Local Arbiter |
2 | ||
3 | The hardware block diagram please check bindings/iommu/mediatek,iommu.txt | |
4 | ||
5 | Required properties: | |
6 | - compatible : must be "mediatek,mt8173-smi-larb" | |
7 | - reg : the register and size of this local arbiter. | |
8 | - mediatek,smi : a phandle to the smi_common node. | |
9 | - power-domains : a phandle to the power domain of this local arbiter. | |
10 | - clocks : Must contain an entry for each entry in clock-names. | |
11 | - clock-names: must contain 2 entries, as follows: | |
12 | - "apb" : Advanced Peripheral Bus clock, It's the clock for setting | |
13 | the register. | |
14 | - "smi" : It's the clock for transfer data and command. | |

16 | Example: | |
17 | larb1: larb@16010000 { | |
18 | compatible = "mediatek,mt8173-smi-larb"; | |
19 | reg = <0 0x16010000 0 0x1000>; | |
20 | mediatek,smi = <&smi_common>; | |
21 | power-domains = <&scpsys MT8173_POWER_DOMAIN_VDEC>; | |
22 | clocks = <&vdecsys CLK_VDEC_CKEN>, | |
23 | <&vdecsys CLK_VDEC_LARB_CKEN>; | |
24 | clock-names = "apb", "smi"; | |
25 | }; |
