+* 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>;
+ };
