From 8261d961d1f397925d7a470864c14663d01ed714 Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Mon, 9 Nov 2015 09:13:59 +0200 Subject: iio: core: Introduce IIO configfs support This patch creates the IIO configfs root group. The group will appear under /iio/, usually /config/iio. We introduce configfs support in IIO in order to be able to easily create IIO objects from userspace. The first supported IIO objects are triggers introduced with next patches.
