All DSS versions contain DSS Core and DISPC, but -the encoder modules vary. - -The DSS Core is the parent of the other DSS modules, and manages clock routing, -integration to the SoC, etc. - -DISPC is the display controller, which reads pixels from the memory and outputs -a RGB pixel stream to encoders. - -The encoder modules encode the received RGB pixel stream to a video output like -HDMI, MIPI DPI, etc. - -Video Ports ------------ - -The DSS Core and the encoders have video port outputs. The structure of the -video ports is described in Documentation/devicetree/bindings/graph.txt, -and the properties for the ports and endpoints for each encoder are -described in the SoC's DSS binding documentation. - -The video ports are used to describe the connections to external hardware, like -panels or external encoders. - -Aliases -------- - -The board dts file may define aliases for displays to assign "displayX" style -name for each display.
