1DT bindings for Xilinx video IP cores
2-------------------------------------
3
4Xilinx video IP cores process video streams by acting as video sinks and/or
5sources. They are connected by links through their input and output ports,
6creating a video pipeline.
7
8Each video IP core is represented by an AMBA bus child node in the device
9tree using bindings documented in this directory. Connections between the IP
10cores are represented as defined in ../video-interfaces.txt.
11
12The whole  pipeline is represented by an AMBA bus child node in the device
13tree using bindings documented in ./xlnx,video.txt.

15Common properties
16-----------------
17
18The following properties are common to all Xilinx video IP cores.
19
20- xlnx,video-format: This property represents a video format transmitted on an
21  AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
22  Video IP and System Design Guide" [UG934]. How the format relates to the IP
23  core is described in the IP core bindings documentation.
24
25- xlnx,video-width: This property qualifies the video format with the sample
26  width expressed as a number of bits per pixel component. All components must
27  use the same width.
28
29- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
30  describes the sensor's color filter array pattern. Supported values are
31  "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
32  defaults to "mono".
