If i keep gpioX bank enabled in A7 device tree, I am not getting interrupt on M4 side on other pins of same GPIO Bank. I need to share gpio bank between A7 and M4 to get interrupt from different peripheral on different processor.(A7 and M4).

 

How can i achieve it? Please let me know your thought on it.
