+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 = < MT8173_POWER_DOMAIN_MM>;
+   clocks = < CLK_MM_SMI_COMMON>,
+< CLK_MM_SMI_COMMON>;
+   clock-names = "apb", "smi";
+   };
