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>;
};
};
