Current dts files for Rockchip with 'vpu' nodes
are manually verified. In order to automate this process
rockchip-vpu.txt has to be converted to yaml.

Changed:
  Add missing reg property

-device-tree bindings for rockchip VPU codec
-
-Rockchip (Video Processing Unit) present in various Rockchip platforms,
-such as RK3288, RK3328 and RK3399.
-
-Required properties:
-- compatible: value should be one of the following
-		"rockchip,rk3288-vpu";
-		"rockchip,rk3328-vpu";
-		"rockchip,rk3399-vpu";
-- interrupts: encoding and decoding interrupt specifiers
-- interrupt-names: should be
-		"vepu", "vdpu" on RK3288 and RK3399,
-		"vdpu" on RK3328.
-- clocks: phandle to VPU aclk, hclk clocks
-- clock-names: should be "aclk" and "hclk"
-- power-domains: phandle to power domain node
-- iommus: phandle to a iommu node
-
-Example:
-SoC-specific DT entry:
-	vpu: video-codec@ff9a0000 {
-		compatible = "rockchip,rk3288-vpu";
-		reg = <0x0 0xff9a0000 0x0 0x800>;
-		interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>,
-			     <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>;
-		interrupt-names = "vepu", "vdpu";
-		clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>;
-		clock-names = "aclk", "hclk";
-		power-domains = <&power RK3288_PD_VIDEO>;
-		iommus = <&vpu_mmu>;
-	};
-
-	vpu: video-codec@ff350000 {
-		compatible = "rockchip,rk3328-vpu";
-		reg = <0x0 0xff350000 0x0 0x800>;
-		interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>;
-		interrupt-names = "vdpu";
-		clocks = <&cru ACLK_VPU>, <&cru HCLK_VPU>;
-		clock-names = "aclk", "hclk";
-		power-domains = <&power RK3328_PD_VPU>;
-		iommus = <&vpu_mmu>;
-	};
