Renesas R-Car Image Renderer (Distortion Correction Engine)

-----------------------------------------------------------



The image renderer, or the distortion correction engine, is a drawing processor

with a simple instruction system capable of referencing video capture data or

data in an external memory as 2D texture data and performing texture mapping

and drawing with respect to any shape that is split into triangular objects.



Required properties:



- compatible: "renesas,<soctype>-imr-lx4", "renesas,imr-lx4" as a fallback for

  the image renderer light extended 4 (IMR-LX4) found in the R-Car gen3 SoCs,

  where the examples with <soctype> are:

  - "renesas,r8a7795-imr-lx4" for R-Car H3,

  - "renesas,r8a7796-imr-lx4" for R-Car M3-W.

- reg: offset and length of the register block;

- interrupts: single interrupt specifier;

- clocks: single clock phandle/specifier pair;

- power-domains: power domain phandle/specifier pair;

- resets: reset phandle/specifier pair.



Example:



	imr-lx4@fe860000 {

		compatible = "renesas,r8a7795-imr-lx4", "renesas,imr-lx4";

		reg = <0 0xfe860000 0 0x2000>;

		interrupts = <GIC_SPI 192 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&cpg CPG_MOD 823>;

		power-domains = <&sysc R8A7795_PD_A3VC>;

		resets = <&cpg 823>;

	};
