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/video/video- +ports.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.
