+* Marvell Real Time Clock controller
+
+Required properties:
+- compatible: should be "mrvl,sa1100-rtc"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- interrupts: Should be two. The first interrupt number is the rtc alarm
+  interrupt and the second interrupt number is the rtc hz interrupt.
+- interrupt-names: Assign name of irq resource.
+
+Example:
+       rtc: rtc@d4010000 {
+               compatible = "mrvl,mmp-rtc";
+               reg = <0xd4010000 0x1000>;
+               interrupts = <5>, <6>;
+               interrupt-name = "rtc 1Hz", "rtc alarm";
+       };
