-Required properties:
-
-- compatible: should be one of:
-	"fsl,imx8-ddr-pmu"
-	"fsl,imx8m-ddr-pmu"
-	"fsl,imx8mp-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>;
