This patchset does the following 3 things: 1) Fixes the RTC DT node name for Exynos5250 SoC 2) Update the "status" property of RTC DT node for Exynos5250 SoC 3) Adds RTC DT node to Exynos5420 SoC
changes since v4: - removed "status" property of RTC DT node from exynos5250 board dts files
changes since v3: - split the 5250 related modifications into 2 separate patch as suggested by Tomasz Figa t.figa@samsung.com
changes since v2: - split the 5250 related modifications into a separate patch. - placed the RTC node as per the alphabetical order in the DTS file as suggested by Kukjin Kim kgene@kernel.org.
changes since v1: - made DT node status as "okay" in the dtsi file itself.

This patch should also rename any other occurencies of rtc node in board dts files, because otherwise it breaks RTC support in bisections.
Otherwise the whole series looks fine to me.
Best regards, Tomasz
Moves the RTC DT node's "status" property from exynos5250 board (arndale & snow) dts files to exynos5250.dtsi, since the bindings in exynos5250.dtsi depicts the RTC h/w completely.
