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