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