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";
|
|
};
