We have developed a dual channel video card by help of jetson Tx-2 Eval board design. So for interrupt we are using TCA9539 GPIO Expander.
As I can see that in attached schematic U28.19 and U28.20 is configured as input and use for interrupt.
I downloaded L4T and tried to understand interrupt implementation in the device tree but did not found any reference for the same.
Please provided reference device tree source file where i can configure TCA9539 pins as input and used for interrupt purpose.
Looking forward for your kind support.
Thanks and Regards,
