+* Renesas JPEG Processing Unit
+
+The JPEG processing unit (JPU) incorporates the JPEG codec with an encoding
+and decoding function conforming to the JPEG baseline process, so that the JPU
+can encode image data and decode JPEG data quickly.
+
+Required properties:
+- compatible: "renesas,jpu-<soctype>", "renesas,rcar-gen2-jpu" as fallback.
+	Examples with soctypes are:
+	  - "renesas,jpu-r8a7790" for R-Car H2
+	  - "renesas,jpu-r8a7791" for R-Car M2-W
+	  - "renesas,jpu-r8a7792" for R-Car V2H
+	  - "renesas,jpu-r8a7793" for R-Car M2-N
+
+  - reg: Base address and length of the registers block for the JPU.
+  - interrupts: JPU interrupt specifier.
+  - clocks: A phandle + clock-specifier pair for the JPU functional clock.
+
+Example: R8A7790 (R-Car H2) JPU node
+	jpeg-codec@fe980000 {
+		compatible = "renesas,jpu-r8a7790", "renesas,rcar-gen2-jpu";
+		reg = <0 0xfe980000 0 0x10300>;
+		interrupts = <0 272 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&mstp1_clks R8A7790_CLK_JPU>;
+	};
