+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>;
+ };
