Extend the S3C RTC node with rtc_src clock so it could be operational. The rtc_src clock is provided by MAX77686 (Trats2) or S2MPS11 (Arndale Octa). Signed-off-by: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx> Reviewed-by: Javier Martinez Canillas <javier.martinez@xxxxxxxxxxxxxxx> --- Patch depends on new file "dt-bindings/clock/samsung,s2mps11.h" from: 1. ARM: dts: Add bindings for 32kHz clocks from s2mps11 http://www.spinics.net/lists/linux-samsung-soc/msg43345.html Changes since v1: 1. Add Javier's reviewed-by. 2.
