18c2ecf20Sopenharmony_ciDT bindings for Xilinx video IP cores 28c2ecf20Sopenharmony_ci------------------------------------- 38c2ecf20Sopenharmony_ci 48c2ecf20Sopenharmony_ciXilinx video IP cores process video streams by acting as video sinks and/or 58c2ecf20Sopenharmony_cisources. They are connected by links through their input and output ports, 68c2ecf20Sopenharmony_cicreating a video pipeline. 78c2ecf20Sopenharmony_ci 88c2ecf20Sopenharmony_ciEach video IP core is represented by an AMBA bus child node in the device 98c2ecf20Sopenharmony_citree using bindings documented in this directory. Connections between the IP 108c2ecf20Sopenharmony_cicores are represented as defined in ../video-interfaces.txt. 118c2ecf20Sopenharmony_ci 128c2ecf20Sopenharmony_ciThe whole pipeline is represented by an AMBA bus child node in the device 138c2ecf20Sopenharmony_citree using bindings documented in ./xlnx,video.txt. 148c2ecf20Sopenharmony_ci 158c2ecf20Sopenharmony_ciCommon properties 168c2ecf20Sopenharmony_ci----------------- 178c2ecf20Sopenharmony_ci 188c2ecf20Sopenharmony_ciThe following properties are common to all Xilinx video IP cores. 198c2ecf20Sopenharmony_ci 208c2ecf20Sopenharmony_ci- xlnx,video-format: This property represents a video format transmitted on an 218c2ecf20Sopenharmony_ci AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream 228c2ecf20Sopenharmony_ci Video IP and System Design Guide" [UG934]. How the format relates to the IP 238c2ecf20Sopenharmony_ci core is described in the IP core bindings documentation. 248c2ecf20Sopenharmony_ci 258c2ecf20Sopenharmony_ci- xlnx,video-width: This property qualifies the video format with the sample 268c2ecf20Sopenharmony_ci width expressed as a number of bits per pixel component. All components must 278c2ecf20Sopenharmony_ci use the same width. 288c2ecf20Sopenharmony_ci 298c2ecf20Sopenharmony_ci- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property 308c2ecf20Sopenharmony_ci describes the sensor's color filter array pattern. Supported values are 318c2ecf20Sopenharmony_ci "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern 328c2ecf20Sopenharmony_ci defaults to "mono". 338c2ecf20Sopenharmony_ci 348c2ecf20Sopenharmony_ci 358c2ecf20Sopenharmony_ci[UG934] https://www.xilinx.com/support/documentation/ip_documentation/axi_videoip/v1_0/ug934_axi_videoIP.pdf 36
