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,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

- touchscreen-inverted-y
|
||||
- touchscreen-size-x
|
||||
- touchscreen-size-y
|
