-Device tree bindings for Goodix GT9xx series touchscreen controller
-
-Required properties:
-
- - compatible : Should be "goodix,gt1151"
- or "goodix,gt5663"
- 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
- - touchscreen-inverted-y
- - touchscreen-size-x
- - touchscreen-size-y
- - touchscreen-swapped-x-y
-
-The touchscreen-* properties are documented in touchscreen.txt in this
-directory.
-
-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>;
- };
-
- /* ... */
- };
