| Device tree bindings for Goodix GT9xx series touchscreen controller |
| |
| Required properties: |
| |
| - compatible : Should be "goodix,gt1151" |
| or "goodix,gt5688" |
| or "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 |
| - interrupts : Interrupt to which the chip is connected |
| |
| Optional properties: |
| |
| - irq-gpios : GPIO pin used for IRQ. The driver uses the |
| interrupt gpio pin as output to reset the device. |
| - reset-gpios : GPIO pin used for reset |
| |
| - AVDD28-supply : Analog power supply regulator on AVDD28 pin |
| - VDDIO-supply : GPIO power supply regulator on VDDIO pin |
| |
| - touchscreen-inverted-x : X axis is inverted (boolean) |
| - touchscreen-inverted-y : Y axis is inverted (boolean) |
| - touchscreen-swapped-x-y : X and Y axis are swapped (boolean) |
| (swapping is done after inverting the axis) |
| |
| Example: |
| |
| i2c@00000000 { |
| /* ... */ |
| |
| gt928@5d { |
| compatible = "goodix,gt928"; |
| reg = <0x5d>; |
| interrupt-parent = <&gpio>; |
| interrupts = <0 0>; |
| |
| irq-gpios = <&gpio1 0 0>; |
| reset-gpios = <&gpio1 1 0>; |
| }; |
| |
| /* ... */ |
| }; |
