eLCDIF is a different display controller that is found on other i.MX SoCs like imx23/imx28/imx6sl/imx6sx. On imx6q/dl the display controller is the IPU. In order to drive a parallel display using the IPU on imx6dl you need to pass compatible = "fsl,imx-parallel-display"; Please see some dts as examples, such as arch/arm/boot/dts/imx6qdl-pico.dtsi. It is also recommended to add an entry for the panel you are using inside drivers/gpu/drm/panel/panel-simple.c
