Hello Everyone,

We are using HE 922(Atom X3-C3200) module with Yocto BSP MR4.1 and finding issues configuring EINT capable interrupt pins for GPIO functionality. Required gpio, direction and output settings are configured in the BSP device tree /arch/x86/boot/dts, but unable to see it reflecting in the Linux OS.

We have also tried configuring gpio using /sys/class/gpio/export mechanism, and is showing error "Can't bind gpio to interrupt". We have this issue on GPIO72, but can be reproduced for any EINT capable pins.

Appreciate your valuable help & suggestion to resolve this issue.

Thank you..
