-* 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 Gen2, R-Car Gen3, RZ/G1, and RZ/G2 SoCs.
-
-Required properties:
-
-  - compatible: Must contain one of the following values
-    - "renesas,vsp1" for the R-Car Gen2 and RZ/G1 VSP1
-    - "renesas,vsp2" for the R-Car Gen3 and RZ/G2 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>;
