1 Device tree bindings for Goodix GT9xx series touchscreen controller 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) 27 28 Example: 29 30 i2c@00000000 { 31 /* ... */ 32 33 gt928@5d { 34 compatible = "goodix,gt928"; 35 reg = <0x5d>; 36 interrupt-parent = <&gpio>; 37 interrupts = <0 0>; 38 39 irq-gpios = <&gpio1 0 0>; 40 reset-gpios = <&gpio1 1 0>; 41 }; 42 43 /* ... */ 44 };
