This should be done via pinctrl irq if possible instead of specifying WAKEUP_EN here, You had some trouble to understand how it can be done, and we agreed to add the wakeup functionality as a follow-up concentrating just on that detail and for now just remove WAKEUP_EN.

Something is strange here, so also the idea in our earlier discussion was to also postpone it and maybe separately discuss it with iio. Regards, Andreas
