1df330515SLaurent PinchartDT bindings for Xilinx video IP cores 2df330515SLaurent Pinchart------------------------------------- 3df330515SLaurent Pinchart 4df330515SLaurent PinchartXilinx video IP cores process video streams by acting as video sinks and/or 5df330515SLaurent Pinchartsources. They are connected by links through their input and output ports, 6df330515SLaurent Pinchartcreating a video pipeline. 7df330515SLaurent Pinchart 8df330515SLaurent PinchartEach video IP core is represented by an AMBA bus child node in the device 9df330515SLaurent Pincharttree using bindings documented in this directory. Connections between the IP 10df330515SLaurent Pinchartcores are represented as defined in ../video-interfaces.txt. 11df330515SLaurent Pinchart 12df330515SLaurent PinchartThe whole pipeline is represented by an AMBA bus child node in the device 13df330515SLaurent Pincharttree using bindings documented in ./xlnx,video.txt. 14df330515SLaurent Pinchart 15df330515SLaurent PinchartCommon properties 16df330515SLaurent Pinchart----------------- 17df330515SLaurent Pinchart 18df330515SLaurent PinchartThe following properties are common to all Xilinx video IP cores. 19df330515SLaurent Pinchart 20df330515SLaurent Pinchart- xlnx,video-format: This property represents a video format transmitted on an 21df330515SLaurent Pinchart AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream 22df330515SLaurent Pinchart Video IP and System Design Guide" [UG934]. How the format relates to the IP 23511257e6SEric Engestrom core is described in the IP core bindings documentation. 24df330515SLaurent Pinchart 25df330515SLaurent Pinchart- xlnx,video-width: This property qualifies the video format with the sample 26df330515SLaurent Pinchart width expressed as a number of bits per pixel component. All components must 27df330515SLaurent Pinchart use the same width. 28df330515SLaurent Pinchart 29df330515SLaurent Pinchart- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property 30df330515SLaurent Pinchart describes the sensor's color filter array pattern. Supported values are 31df330515SLaurent Pinchart "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern 32df330515SLaurent Pinchart defaults to "mono". 33df330515SLaurent Pinchart 34df330515SLaurent Pinchart 3554b0e2ebSAlexander A.
