+* Samsung's S3C Real Time Clock controller
+
+Required properties:
+- compatible: should be one of the following.
+ * "samsung,s3c2410-rtc" - for controllers compatible with s3c2410 rtc.
+ * "samsung,s3c6410-rtc" - for controllers compatible with 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 interupt and second interrupt number
+ is the rtc tick interrupt. The number of cells representing a interrupt
+ depends on the parent interrupt controller.
+
+Example:
+
+ rtc@10070000 {
+ compatible = "samsung,s3c6410-rtc";
+ reg = <0x10070000 0x100>;
+ interrupts = <44 0 45 0>;
+ };
