Hi, I've tried googling again and again. But I can't seem to find out how to use GPIO triggers with the ADC driver. I am using a patched am335x driver and kernel version 3.11. I can use sysfs triggers to trigger and read a buffer of samples easily. But I cannot figure out how to connect a gpio to trigger the driver. Is it some additional support to add to the driver? Or am I missing something very obvious.. Can someone spare a few minutes and point me in the right direction?
