Xilinx V4L2 REMAPPER driver


The purpose of this page is to describe the Linux V4L2 driver for Xilinx Remapper(REMAPPER) soft IP.

Overview

The Linux REMAPPER driver (xilinx-remapper.c) based on the V4L2 framework creates a subdev node(/dev/v4l-subdev*) which can be used to configure the REMAPPER IP core. The general description of V4L2 framework is documented here, v4l2-framework.txt.

Linux Kernel defconfig

CONFIG_VIDEO_XILINX_REMAPPER and CONFIG_VIDEO_XILINX should be enabled.

Device tree binding

The dts node should be defined with correct hardware configuration. How to define the node is documented here, xlnx,axi-remapper.txt.

Supporting features

The REMAPPER IP core remaps the pixel components and doesn't require any programming. The V4L2 REMAPPER driver provides to model the hardware pipeline more accurately in software.
