+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.

+		spi-3wire;
+		spi-cs-high;
+
+		reset-gpios = <&gpe 2 GPIO_ACTIVE_LOW>;
