+* 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>;
+ };
