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".
