+DT binding for Winstar WG160160
+
+This binding is for the Winstar WG160160 display using a RA8822 controller
+
+Required properties:
+- compatible: "winstar,wg160160"
+- reg: numeric identifier for the display
+
+The node for this driver must be a child node of a parallel-data-bus, hence
+all mandatory properties described in ../pardata/parallel-data-bus.txt
+must be specified.
+
+Optional properties:
+- chipselect-gpios: GPIO used for chipselect of the display
+- reset-gpios: GPIO that can be used to do a hardware reset of the display
+- backlight: phandle of the backlight device attached to the panel
+- regulator: phandle of the regulator that provides the supply voltage
+
+Example:
+
+ backlight: backlight {
+ compatible = "gpio-backlight";
+ }
+
+ power: regulator@0 {
+ }
+
+ pardatabus {
+ compatible = "parallel-data-bus";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_pardata>;
+ data-gpios = <&pioe 0 GPIO_ACTIVE_HIGH
+ &pioe 1 GPIO_ACTIVE_HIGH
+ &pioe 2 GPIO_ACTIVE_HIGH
+ &pioe 3 GPIO_ACTIVE_HIGH
+ &pioe 4 GPIO_ACTIVE_HIGH
+ &pioe 5 GPIO_ACTIVE_HIGH
+ &pioe 6 GPIO_ACTIVE_HIGH
+ &pioe 7 GPIO_ACTIVE_HIGH>;
+ enable-gpios = <&pioe 8 GPIO_ACTIVE_HIGH>;
+ rs-gpios = <&pioe 12 GPIO_ACTIVE_HIGH>;
+ readdwrite-gpios = <&pioe 11 GPIO_ACTIVE_HIGH>;
+
+ wg160160@0 {
+ compatible = "winstar,wg160160";
+ reg = <1>;
+ reset-gpios = <&pioe 13 GPIO_ACTIVE_LOW>;
+ chipselect-gpios = <&pioe 9 GPIO_ACTIVE_LOW>;
+ backlight = &backlight;
+ power = &power;
+ }
+ }
