King Display KD035G6-54NT 3.5" (320x240 pixels) 24-bit TFT LCD panel
Required properties:
- compatible: should be "kingdisplay,kd035g6-54nt"
- power-supply: See panel-common.txt
- reset-gpios: See panel-common.txt
Optional properties:
- backlight: see panel-common.txt
The generic bindings for the SPI slaves documented in [1] also apply.
The device node can contain one 'port' child node with one child
'endpoint' node, according to the bindings defined in [2]. This
node should describe panel's video bus.
[1]: Documentation/devicetree/bindings/spi/spi-bus.txt
[2]: Documentation/devicetree/bindings/graph.txt
Example:
&spi {
panel@0 {
compatible = "kingdisplay,kd035g6-54nt";
reg = <0>;
spi-max-frequency = <3125000>;
spi-3wire;
spi-cs-high;
reset-gpios = <&gpe 2 GPIO_ACTIVE_LOW>;
backlight = <&backlight>;
power-supply = <&ldo6>;
port {
panel_input: endpoint {
remote-endpoint = <&panel_output>;
};
};
};
};
