+* Freescale(NXP) IMX8 DDR performance monitor
+
+Required properties:
+
+- compatible: should be one of:
+	"fsl,imx8-ddr-pmu"
+	"fsl,imx8m-ddr-pmu"
+
+- reg: physical address and size
+
+- interrupts: single interrupt
+	generated by the control block
+
+Example:
+
+	ddr-pmu@5c020000 {
+		compatible = "fsl,imx8-ddr-pmu";
+		reg = <0x5c020000 0x10000>;
+		interrupt-parent = <&gic>;
+		interrupts = <GIC_SPI 131 IRQ_TYPE_LEVEL_HIGH>;
+	};
