[PATCH 2/2] ARM: dts: Enable S3C RTC on Trats2, Odroid-U3 and Arndale Octa
From: Krzysztof Kozlowski
Date: Thu Apr 02 2015 - 07:03:35 EST
Extend the S3C RTC node with rtc_src clock so it could be operational.
The rtc_src clock is provided by MAX77686 (Trats2 and Odroid-U3) or
S2MPS11 (Arndale Octa).
