Hi nathanzhangbq,
Are you using the devkit or custom board for AGX Orin?

Could you try configure them as following instead?
```auto
zzz_irq_device: zzz_irq_device@5A {
compatible = "nvidia,tegra234-zzz-irq";
reg = <0x5A>;
- interrupt-parent = <&gpio_aon>;

Please share the full device tree rather than just the overlay.
You can simply run the following command on your board and share `extracted_proc.dts` for further check.
```auto
$ sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree
```

Hi Kevin,
Here is the console log with panic info and dts.

Sorry that you may need to revert it back to original configuration as the cell of interrupts property is 2.
```auto
zzz_irq_device: zzz_irq_device@5A {
compatible = "nvidia,tegra234-zzz-irq";
reg = <0x5A>;
interrupt-parent = <&gpio_aon>;
interrupts = ;
status = "okay";
};
```
Please also run the following command to check if this GPIO(i.e. PBB.00) is used by other driver.
```auto
$ sudo cat /sys/kernel/debug/gpio|grep PBB.00
```

Hi Kevin,
here is the dmesg and dts info. Following your command :
```auto
$ sudo cat /sys/kernel/debug/gpio|grep PBB.00
gpio-324 (PBB.00 )
$ sudo cat /sys/kernel/debug/gpio|grep PEE.04
gpio-343 (PEE.04 |Power ) in hi IRQ ACTIVE LOW
```
and the dmesg info should be noted:
```auto

[14.795560] hwmon hwmon8: temp1_input not attached to any thermal zone

```
and the kernel ./arch/arm64/deconfig ignore the macro “CONFIG\_GPIOLIB”, but the ./.config set the macro “CONFIG\_GPIOLIB=y”, Is this discrepancy normal? Should we configure this macro?

It should be fine if CONFIG\_GPIOLIB is enabled in .config.
You can also run the following command on your board to check its configuration.
```auto
$ zcat /proc/config.gz |grep CONFIG_GPIOLIB
```

Could you try using `platform_get_irq()` as following instead?
```auto
data->irq = platform_get_irq(pdev, 0);
if (data->irq < 0) {
dev_err(dev, "Failed to get IRQ from DTS: %d\n", data->irq);
return data->irq;
}
```

Hi Kevin,
modify dts property:
```auto
/ {
fragment@0 {
__overlay__ {
zzz_irq_device: zzz_irq_device {
compatible = "nvidia,tegra234-zzz-irq";
interrupt-parent = <&gpio_aon>;
interrupts = ;
status = "okay";
};
...
}
}
}
```
and the platform driver probe completed, but the platform\_get\_irq(pdev, 0) function return value(253), so 253 is the PBB.00-irq value? and the interrupt handler is not work as expected.
Here is console info:
```auto
[8.622810] tegra234-zzz-irq zzz_irq_device: Virtual I2C device probed, IRQ: 253
gaxorin@gaxorin-desktop:/sys/firmware/devicetree/base/zzz_irq_device$ cat interrupts
gaxorin@gaxorin-desktop:/sys/firmware/devicetree/base/zzz_irq_device$ cat interrupt-parent
gaxorin@gaxorin-desktop:/sys/firmware/devicetree/base/zzz_irq_device$ sudo cat /sys/kernel/debug/gpio|grep PBB.00
gpio-324 (PBB.00 )
gaxorin@gaxorin-desktop:/sys/firmware/devicetree/base/zzz_irq_device$
```

Yes, it seems you can probe the driver correctly.
Please simply run the following command to check the IRQ.
```auto
$ cat /proc/interrupts |grep 253
```
> [@nathanzhangbq](#):

Do you mean that there’s no interrupt count when the IRQ is triggered?
Or your handler is not working when there’s the interrupt?
