+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>;
+ interrupt-parent = <&msm_gpio>;
+ interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
+ 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>;
