1 | SMI (Smart Multimedia Interface) Common |
2 | ||
3 | The hardware block diagram please check bindings/iommu/mediatek,iommu.txt | |
4 | ||
5 | Required properties: | |
6 | - compatible : must be "mediatek,mt8173-smi-common" | |
7 | - reg : the register and size of the SMI block. | |
8 | - power-domains : a phandle to the power domain of this local arbiter. | |
9 | - clocks : Must contain an entry for each entry in clock-names. | |
10 | - clock-names : must contain 2 entries, as follows: | |
11 | - "apb" : Advanced Peripheral Bus clock, It's the clock for setting | |
12 | the register. | |
13 | - "smi" : It's the clock for transfer data and command. | |
14 | They may be the same if both source clocks are the same. | |
15 | ||
16 | Example: | |
17 | smi_common: smi@14022000 { | |
18 | compatible = "mediatek,mt8173-smi-common"; | |
19 | reg = <0 0x14022000 0 0x1000>; | |
20 | power-domains = <&scpsys MT8173_POWER_DOMAIN_MM>; | |
21 | clocks = <&mmsys CLK_MM_SMI_COMMON>, | |
22 | <&mmsys CLK_MM_SMI_COMMON>; | |
23 | clock-names = "apb", "smi"; | |
24 | }; |
