Each video IP core is represented as documented in video.txt +and IP core specific documentation, xlnx,v-*.txt, in this directory. The DT +node of the VIPP represents as a top level node of the pipeline and defines +mappings between DMAs and the video IP cores. + +Required properties: + +- compatible: Must be "xlnx,video". + +- dmas, dma-names: List of one DMA specifier and identifier string (as defined + in Documentation/devicetree/bindings/dma/dma.txt) per port. Each port + requires a DMA channel with the identifier string set to "port" followed by + the port index. + +- ports: Video port, using the DT bindings defined in ../video-interfaces.txt. + +Required port properties: + +- direction: should be either "input" or "output" depending on the direction + of stream. + +Example: + + video_cap { + compatible = "xlnx,video"; + dmas = <&vdma_1 1>, <&vdma_3 1>; + dma-names = "port0", "port1"; + + ports { + #address-cells = <1>; + #size-cells = <0>; + + port@0 { + reg = <0>; + direction = "input"; + vcap0_in0: endpoint { + remote-endpoint = <&scaler0_out>; + }; + }; + port@1 { + reg = <1>; + direction = "input"; + vcap0_in1: endpoint { + remote-endpoint = <&switch_out1>; + }; + }; + }; + }; -- cgit v1.2.3
