* 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>;
|
|
};
