+EMI (External Memory Interface)
+
+Required properties:
+- compatible : must be one of :
+	"mediatek,mt8183-emi"
+- reg : the register and size of the EMI block.
+- interrupts : includes MPU, CGM, ELM.
+
+Example:
+	emi@10219000 {
+	compatible = "mediatek,mt8183-emi";
+	reg = <0 0x10219000 0 0x1000>, /* CEN EMI */
+		  <0 0x10226000 0 0x1000>, /* EMI MPU */
+		  <0 0x1022d000 0 0x1000>, /* CHA EMI */
+		  <0 0x10235000 0 0x1000>; /* CHB EMI */
+	interrupts = <GIC_SPI 147 IRQ_TYPE_LEVEL_LOW>, /* MPU */
+			 <GIC_SPI 148 IRQ_TYPE_LEVEL_HIGH>, /* CGM */
+			 <GIC_SPI 155 IRQ_TYPE_LEVEL_HIGH>; /* ELM */
+};
