The connections between them can be configured by output + and input selectors in the MMSYS_CONFIG register space. Pixel clock and start + of frame signal are distributed to the other function blocks by a DISP_MUTEX + function block. + All DISP device tree nodes must be siblings to the central MMSYS_CONFIG node. + For a description of the MMSYS_CONFIG binding, see + Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml for details. + + DISP function blocks + ==================== + A display stream starts at a source function block that reads pixel data from + memory and ends with a sink function block that drives pixels on a display + interface, or writes pixels back to memory.
