+Required properties:
+- compatible: Must be "rockchip,rk3399-dfi".
+- reg: physical base address of each DFI and length of memory mapped region
+- rockchip,pmu: phandle to the syscon managing the "pmu general register files"
+- clocks: phandles for clock specified in "clock-names" property
+- clock-names : the name of clock used by the DFI, must be "pclk_ddr_mon";
+
+Example:
+ dfi: dfi@0xff630000 {
+ compatible = "rockchip,rk3399-dfi";
+ reg = <0x00 0xff630000 0x00 0x4000>;
+ rockchip,pmu = <&pmugrf>;
+ clocks = <&cru PCLK_DDR_MON>;
+ clock-names = "pclk_ddr_mon";
