| 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>; |
| }; |
