The display related IPs in MT8195 are flexible and support being interconnected with different instances of DDP IPs and/or with different DDP IPs, forming a full Display Data Path that ends with an actual display output, which is board specific. Add a common graph in the main mt8195.dtsi devicetree, which is shared between all of the currently supported boards. All boards featuring any display functionality will extend this common graph to hook the display controller of the SoC to their specific output port(s).
