1 | Device tree bindings for Goodix GT9xx series touchscreen controller |
| 2 | ||
| 3 | Required properties: | |
| 4 | ||
| 5 | - compatible : Should be "goodix,gt911" | |
| 6 | or "goodix,gt9110" | |
| 7 | or "goodix,gt912" | |
| 8 | or "goodix,gt927" | |
| 9 | or "goodix,gt9271" | |
| 10 | or "goodix,gt928" | |
| 11 | or "goodix,gt967" | |
| 12 | - reg : I2C address of the chip. Should be 0x5d or 0x14 | |
| 13 | - interrupt-parent : Interrupt controller to which the chip is connected | |
| 14 | - interrupts : Interrupt to which the chip is connected | |

16 | Optional properties: |
| 17 | ||
| 18 | - irq-gpios : GPIO pin used for IRQ. The driver uses the | |
| 19 | interrupt gpio pin as output to reset the device. | |
| 20 | - reset-gpios : GPIO pin used for reset | |
| 21 | ||

22 | - touchscreen-inverted-x : X axis is inverted (boolean) |
| 23 | - touchscreen-inverted-y : Y axis is inverted (boolean) | |
| 24 | - touchscreen-swapped-x-y : X and Y axis are swapped (boolean) | |
| 25 | (swapping is done after inverting the axis) | |
