+* 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: should containg one of the following:
+ - "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";
+ reg = <0 0xfe980000 0 0x10300>;
+ interrupts = <0 272 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp1_clks R8A7790_CLK_JPU>;
+ };
