Device tree node for panel(Microtips-Model No: 13-101HIEBCAF0-S) is created, which includes timing parameters of the panel, data-mapping and ports which are read by the code to set bus formats, clock required by the panel. Generic simple_panel driver is being used.
Link dss and panel by setting the port name in remote-endpoint.
main_dss0_pins_default - setting for pinmux.
