integrating touchscreen in kernel

[Ketki]

I am using Goodix Touch driver with Android 9.0 and kernel 4+
I use pin 263 (GPIO4) as interrupt pin .
But I get the following error :

gpio-4 (GTP INT IRQ): _gpiod_direction_output_raw: tried to set a GPIO tied to an IRQ as output

I checked the pin is defined as input pin.So does this mean that some other driver is trying to use it as output pin. If yes how can I find this driver that is occupying the pin. I found an ads7428 driver in the device tree file occupying this pin and I disabled it . Other than that I can't find any other driver using the pin.

Thank You.
