+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 each local arbiter.
+- smi : must be "&smi_common". Refer to bindings/soc/mediatek,smi.txt.
+- clocks : must contain one entry for each clock-names.
+ There are 2 clockes:
+ APB clock : Advanced Peripheral Bus clock, It's the clock for setting
+ the register.
+ SMI clock : It's the clock for transfer data and command.
+- clock-name: must be "apb" and "smi".
+
+Example:
+ larb0:larb@14021000 {
+ compatible = "mediatek,mt8173-smi-larb";
+ reg = <0 0x14021000 0 0x1000>;
+ smi = <&smi_common>;
+ clocks = <&mmsys MM_SMI_LARB0>,
+ <&mmsys MM_SMI_LARB0>;
+ clock-names = "apb", "smi";
+ };
