From c9a865bd47150db0cd3d93e30744783e26c22f6c Mon Sep 17 00:00:00 2001 From: Markus Reichl Date: Fri, 18 Nov 2016 10:55:04 +0100 Subject: [PATCH] ARM: dts: exynos: Add ADCs on 4412 and 5422 based odroid boards. Odroid-X, -X2, -XU3 and -XU4 have SOC-ADC routed to an external connector. Enable the ADC for use as iio-device.
