-* 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
