Annotated Snippet
DT bindings for Xilinx video IP cores
-------------------------------------
Xilinx video IP cores process video streams by acting as video sinks and/or
sources. They are connected by links through their input and output ports,
creating a video pipeline.
Each video IP core is represented by an AMBA bus child node in the device
tree using bindings documented in this directory. Connections between the IP
cores are represented as defined in ../video-interfaces.txt.
The whole pipeline is represented by an AMBA bus child node in the device
tree using bindings documented in ./xlnx,video.txt.
Common properties
-----------------
The following properties are common to all Xilinx video IP cores.
- xlnx,video-format: This property represents a video format transmitted on an
AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
Video IP and System Design Guide" [UG934]. How the format relates to the IP
core is described in the IP core bindings documentation.
- xlnx,video-width: This property qualifies the video format with the sample
width expressed as a number of bits per pixel component. All components must
use the same width.
- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
describes the sensor's color filter array pattern. Supported values are
"bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
defaults to "mono".

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
