X-Git-Tag: v4.10-rc1~82^2~7^2~3
X-Git-Url: https://git.kernel.dk/?p=linux-2.6-block.git;a=commitdiff_plain;h=c9a865bd47150db0cd3d93e30744783e26c22f6c

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.
