From da4d3d6bb9f6047217d549c233303161bb4678d9 Mon Sep 17 00:00:00 2001 From: Alexandru Tachici Date: Mon, 13 Jan 2020 12:26:52 +0200 Subject: iio: adc: ad-sigma-delta: Allow custom IRQ flags Before this patch the ad_sigma_delta implementation hardcoded the irq trigger type to low, assuming that all Sigma-Delta ADCs have the same interrupt-type. This patch allows all drivers using the ad_sigma_delta layer to set the irq trigger type to the one specified in the datasheet.
