   2
   3 Required properties:
   4
   5  - compatible           : Should be "goodix,gt1151"
   6                                  or "goodix,gt911"
   7                                  or "goodix,gt9110"
   8                                  or "goodix,gt912"
   9                                  or "goodix,gt927"
  10                                  or "goodix,gt9271"
  11                                  or "goodix,gt928"
  12                                  or "goodix,gt967"
  13  - reg                  : I2C address of the chip. Should be 0x5d or 0x14
  14  - interrupt-parent     : Interrupt controller to which the chip is connected
  15  - interrupts           : Interrupt to which the chip is connected
  16
  17 Optional properties:
  18
  19  - irq-gpios            : GPIO pin used for IRQ. The driver uses the
  20                           interrupt gpio pin as output to reset the device.
  21  - reset-gpios          : GPIO pin used for reset
  22
  23  - touchscreen-inverted-x  : X axis is inverted (boolean)
  24  - touchscreen-inverted-y  : Y axis is inverted (boolean)
  25  - touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
  26                              (swapping is done after inverting the axis)

  40                         reset-gpios = <&gpio1 1 0>;
  41                 };
