I'm sure about exynos3250 RTC is same with S3C6410 RTC. There was little different about that pevious S3C6410 RTC don't consider to control the 'rtc_src' clk. But, Javier's patch[1] add the '.needs_src_clk' to control the 'rtc_src' clk. After merged this patch, there is no different part between Exynos3250 RTC and S3C6410 RTC.
