-* Samsung's S3C Real Time Clock controller
-
-Required properties:

-    * "samsung,s3c2416-rtc" - for controllers compatible with s3c2416 rtc.

-                                 exynos3250 rtc (use "samsung,s3c6410-rtc").
-- reg: physical base address of the controller and length of memory mapped
-  region.
-- interrupts: Two interrupt numbers to the cpu should be specified. First
-  interrupt number is the rtc alarm interrupt and second interrupt number
-  is the rtc tick interrupt. The number of cells representing a interrupt
-  depends on the parent interrupt controller.
-- clocks: Must contain a list of phandle and clock specifier for the rtc
-          clock and in the case of a s3c6410 compatible controller, also
-          a source clock.
