+* SPEAr RTC
+
+Required properties:
+- compatible : "st,spear600-rtc"
+- reg : Address range of the rtc registers
+- interrupt-parent: Should be the phandle for the interrupt controller
+  that services interrupts for this device
+- interrupt: Should contain the rtc interrupt number
+
+Example:
+
+        rtc@fc000000 {
+                compatible = "st,spear600-rtc";
+                reg = <0xfc000000 0x1000>;
+                interrupt-parent = <&vic1>;
+                interrupts = <12>;
+        };
