+* Renesas VSP Video Processing Engine
+
+The VSP is a video processing engine that supports up-/down-scaling, alpha
+blending, color space conversion and various other image processing features.
+It can be found in the Renesas R-Car second generation SoCs.
+
+Required properties:
+
+  - compatible: Must contain one of the following values
+    - "renesas,vsp1" for the R-Car Gen2 VSP1
+    - "renesas,vsp2" for the R-Car Gen3 VSP2
+
+  - reg: Base address and length of the registers block for the VSP.
+  - interrupts: VSP interrupt specifier.
+  - clocks: A phandle + clock-specifier pair for the VSP functional clock.
+
+Optional properties:
+
+  - renesas,fcp: A phandle referencing the FCP that handles memory accesses
+                 for the VSP. Not needed on Gen2, mandatory on Gen3.
+
+
+Example: R8A7790 (R-Car H2) VSP1-S node
+
+	vsp@fe928000 {
+		compatible = "renesas,vsp1";
+		reg = <0 0xfe928000 0 0x8000>;
+		interrupts = <0 267 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&mstp1_clks R8A7790_CLK_VSP1_S>;
+	};
