Without an entry panel-edp warns at every boot ("Unknown panel BOE 0x0d9b, using conservative timings"). The panel's timing requirements are not published, so use the same delays as the other BOE NE140WUM entries (delay_200_500_e80). With them the panel trains and lights up reliably on this machine.
