I have listed Sergei as the maintainer, as he wrote the original
bindings. Sergei: Please scream if this is inappropriate ;-)
v2:
- Add blank line between paragraphs in description,
- Add "|" to preserve description formatting,
- Add Reviewed-by,
- s/Tree/Device Tree/ in description.

-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>;
- };
