+Kaohsiung Opto-Electronics Inc. 5.7" QVGA (320 x 240) TFT LCD panel
+
+Required properties:
+- compatible: should be "koe,tx14d24vm1bpa"
+- backlight: phandle of the backlight device attached to the panel
+- power-supply: single regulator to provide the supply voltage
+
+Required nodes:
+- port: Parallel port mapping to connect this display
+
+This panel needs single power supply voltage. Its backlight is conntrolled
+via PWM signal.
+
+Example:
+--------
+
+Example device-tree definition when connected to iMX53 based board
+
+ lcd_panel: lcd-panel {
+ compatible = "koe,tx14d24vm1bpa";
+ backlight = <&backlight_lcd>;
+ power-supply = <&reg_3v3>;
+
+ port {
+ lcd_panel_in: endpoint {
+ remote-endpoint = <&lcd_display_out>;
+ };
+ };
+ };
+
+Then one needs to extend the dispX node:
+
+ lcd_display: disp1 {
+
+ port@1 {
+ reg = <1>;
+
+ lcd_display_out: endpoint {
+ remote-endpoint = <&lcd_panel_in>;
+ };
+ };
+ };
