+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 */
