-* Freescale(NXP) IMX8 DDR performance monitor
-
-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>;
- };
