GPIO interrupt driver for multiple GPIO's

Honored Contributor II


The alter provided gpio_interrupt driver only allows mapping of one gpio to one interrupt. Is there a way I can combine multiple gpio's - all the push buttons on helio board to give one interrupt.  

For example, if there is any change in value on any of the pushbuttons, one interrupt callback function is called. Right now, I can only attach one gpio to one interrupt at a time.
