			Toppoly TD028TTEC1 Panel
			========================

			Required properties:
			- compatible: "toppoly,td028ttec1"

			Optional properties:
			- label: a symbolic name for the panel

			Required nodes:
			- Video port for DPI input

			Example
			-------

			lcd-panel: td028ttec1@0 {
			compatible = "toppoly,td028ttec1";
			reg = <0>;
			spi-max-frequency = <100000>;
			spi-cpol;
			spi-cpha;

			label = "lcd";
			port {
			lcd_in: endpoint {
			remote-endpoint = <&dpi_out>;
			};
			};
			};
