| 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 decribed 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". |
