How to use Jetson Nano gt911 touchscreen in interrupts mode

[liuzheng89]

Hi,
I would like to add touchscreen via I2C device;
and i connect i2c sensor like below；but the gt911 driver can not into interrtpt mode;
gpio@6000d000 {
gt911_int {
gpio-hog;
input;
gpios = <TEGRA_GPIO(Y,2) GPIO_ACTIVE_HIGH>;
label = “GT911_INT”;
status = “okay”;
};
};
// GPIO12----> GPIO3_PY.02----> Touch_INT
// GPIO13----> GPIO3_PE.06----> Touch_RST
i2c@7000c400 {
gt911@5d {
compatible = “goodix,gt9xx”;
reg = <0x5d>;
interrupt-parent = <&gpio>; // gpio interrupt
interrupts = <TEGRA_GPIO(Y,2) IRQ_TYPE_EDGE_FALLING>; //IRQ_TYPE_EDGE_FALLING
irq-gpio = <&gpio TEGRA_GPIO(Y,2) GPIO_ACTIVE_HIGH>;
rst-gpio= <&gpio TEGRA_GPIO(E,6) GPIO_ACTIVE_HIGH>;
status = “okay”;
};
};

Hi liuzheng89,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

@liuzheng89

but the gt911 driver can not into interrtpt mode;

What do you mean about “can not into interrtpt mode”?

Could you also share the block diagram of your connection?
