title: Renesas R-Car Image Renderer (Distortion Correction Engine)

maintainers:
  - Sergei Shtylyov <sergei.shtylyov@gmail.com>

description: |
  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.

  The image renderer light extended 4 (IMR-LX4) is found in R-Car Gen3 SoCs.
