The purpose of this page is to describe the Linux V4L2 driver for Xilinx Color FIlter Array(CFA) soft IP.
NOTE: This IP has been superseded by the Demosaic and users should look at the Xilinx V4L2 Demosaic driver
page for the latest driver information.
The Linux TPG driver (xilinx-cfa.c
) is based on the V4L2 framework, and creates a subdev node(/dev/v4l-subdev*) which can be used to configure the CFA IP core. The general description of V4L2 framework is documented here, v4l2-framework.txt
Linux Kernel defconfig
CONFIG_VIDEO_XILINX_CFA 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-cfa.txt
All CFA features are supported including:
- Converting Bayer phases(RGGB, GRBG, GBRG, BGGR) into RGB888
