+Device tree bindings for Goodix GTx5 series touchscreen controller
+
+Required properties:
+
+- compatible : should be "goodix,gtx5" or "goodix,gsx"
+
+- reg : I2C address of the chip. Should be 0x5d or 0x14
+- interrupt-parent : Inerrupt controller to which the chip is connected
+- interrupts : Interrrupt 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.
+- irq-gpios : interrupt gpio.
+- irq-flags : irq trigger type config, value should be:
+ 1 - rising edge,
+ 2 - falling edge,
+ 4 - high level,
+ 5 - low level.
+- touchscreen-swapped-x-y: swap x/y axis coordinates.
+- touchscreen-key-map: keycode value map /*KEY_HOMEPAGE, KEY_BACK*/
+- power-on-delay-us: delay after power on.
+- power-off-delay-us: delay after power off.
+- normal-cfg: touch device normal config data.
+- vtouch-supply : power supply for the touch device.
