Geert Uytterhoeven May 19, 2021, 1 p.m. UTC 
Convert the Renesas JPEG Processing Unit Device Tree binding
documentation to json-schema.

Document missing properties.
Update the example to match reality.

I have listed Mikhail as the maintainer, as he wrote the original driver
and bindings.  Mikhail: Please scream if this is inappropriate ;-)

-* 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";

-		interrupts = <0 272 IRQ_TYPE_LEVEL_HIGH>;
