+Device tree bindings for Goodix GT9xx series touchscreen controller
+
+Required properties:
+
+ - compatible          : Should be "goodix,gt911"
+                                or "goodix,gt9110"
+                                or "goodix,gt912"
+                                or "goodix,gt927"
+                                or "goodix,gt9271"
+                                or "goodix,gt928"
+                                or "goodix,gt967"
+ - 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
+
+Example:
+
+       i2c@00000000 {
+               /* ... */
+
+               gt928@5d {
+                       compatible = "goodix,gt928";
+                       reg = <0x5d>;
+                       interrupt-parent = <&gpio>;
+                       interrupts = <0 0>;
+               };

+               /* ... */
