Xilinx V4L2 Switch driver


Xilinx V4L2 Switch driver


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

Overview

The Linux RGB2YUV driver (xilinx-switch.c) based on the V4L2 framework creates a subdev node(/dev/v4l-subdev*) which can be used to configure the SWITCH IP core. The general description of V4L2 framework is documented here, v4l2-framework.txt.

Linux Kernel defconfig

CONFIG_VIDEO_XILINX_SWITCH 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-switch.txt.

Supporting features

The SWITCH IP core provides to program routing from N inputs to M outputs, and the V4L2 SWITCH driver allows to control the IP core using the standard V4L2 API.
