SMI (Smart Multimedia Interface) Common
The hardware block diagram please check bindings/iommu/mediatek,iommu.txt
Required properties:
- compatible : must be "mediatek,mt8173-smi-common"
- reg : the register and size of the SMI block.
- 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.
They may be the same if both source clocks are the same.
Example:
smi_common: smi@14022000 {
compatible = "mediatek,mt8173-smi-common";
reg = <0 0x14022000 0 0x1000>;
power-domains = <&scpsys MT8173_POWER_DOMAIN_MM>;
clocks = <&mmsys CLK_MM_SMI_COMMON>,
<&mmsys CLK_MM_SMI_COMMON>;
clock-names = "apb", "smi";
};
SMI (Smart Multimedia Interface) Local Arbiter
The hardware block diagram please check bindings/iommu/mediatek,iommu.txt
Required properties:
- compatible : must be "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.
Example:
larb1: larb@16010000 {
compatible = "mediatek,mt8173-smi-larb";
reg = <0 0x16010000 0 0x1000>;
mediatek,smi = <&smi_common>;
power-domains = <&scpsys MT8173_POWER_DOMAIN_VDEC>;
clocks = <&vdecsys CLK_VDEC_CKEN>,
<&vdecsys CLK_VDEC_LARB_CKEN>;
clock-names = "apb", "smi";
};
