+Device tree bindings for Goodix GTx5 series touchscreen controller
+
+Required properties:
+
+- compatible		: Should be "goodix,gt7589"
+				 or "goodix,gt8589"
+			         or "goodix,gt9589"
+- reg			: I2C address of the chip. Should be 0x5d or 0x14
+- interrupt-parent	: Interrupt controller to which the chip is connected
+- interrupts		: Interrupt to which the chip is connected
+- touchscreen-size-x	: horizontal resolution of touchscreen(in pixels)
+- touchscreen-size-y	: vertical resolution of touchscreen(in pixels)
+- touchscreen-max-id	: panel supported max touch number.
+- touchscreen-max-w	: panel max width value.
+
+Optional properties:
+- reset-gpios		  : reset gpio.
+- touchscreen-swapped-x-y : swap  x/y axis coordinates.
+- linux,keycodes	  : Specifies an array of numeric keycode values to
+			    be used for reporting button presses. The array can
+			    contain up to 8 entries.
+- goodix,normal-cfg-X	  : touch device normal config data, this config data is
+		            touchpanel manufacturer related. normal-cfg-X, X
+			    represent for a panel manufacturer, X is less than 10.
+- vtouch-supply		  : power supply for the touch device.
+
+Example:
+i2c@00000000 {
+	/* ... */
+
+	gt8589@14 {
+		compatible = "goodix,gt8589";
+		reg = <0x14>;

+		vtouch-supply = <&pm8916_l15>;
+		reset-gpios = <&msm_gpio 12 0x0>;
+		touchscreen-max-id = <10>;
+		touchscreen-size-x = <400>;
+		touchscreen-size-y = <400>;
+		touchscreen-max-w = <400>;
+		linux,keycodes = <KEY_HOMEPAGE>, <KEY_MENU>, <KEY_BACK>;
