-* Rockchip rk3399 DFI device
-
-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 at ff630000 {
-		compatible = "rockchip,rk3399-dfi";
-		reg = <0x00 0xff630000 0x00 0x4000>;
-		rockchip,pmu = <&pmugrf>;
-		clocks = <&cru PCLK_DDR_MON>;
-		clock-names = "pclk_ddr_mon";
