Xilinx Video IP Pipeline (VIPP)
|
|
-------------------------------
|
|
|
|
General concept
|
|
---------------
|
|
|
|
Xilinx video IP pipeline processes video streams through one or more Xilinx
|
|
video IP cores. 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>;
|
|
};
|
|
};
|
|
};
|
|
};
