+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.
