To support this, we need to add more properties. - Add pinctrls for edptx and dptx. - Add ports for edptx and dptx. The port connections for the internal and external display: dp-intf0 -> edptx -> panel dp-intf1 -> dptx Because it lacks port of panel, so we keep empty remote-endpoint for port1@edptx.
