+Atmel AT91SAM9260 Real Time Timer
+
+Required properties:
+- compatible: should be: "atmel,at91sam9260-rtt"
+- reg: should contain 2 memory regions
+  * the first one encodes the memory region of the RTT controller
+  * the second one encodes the GPBR (General Purpose Backup Resgisters)
+    memory region used to store the current time
+- interrupts: rtc alarm/event interrupt
+- clocks: should contain one clock pointing the the slow clk
+
+Example:
+
+rtc@fffffe00 {
+	compatible = "atmel,at91sam9260-rtt";
+	reg = <0xfffffd20 0x10
+	       0xfffffd50 0x4>;
+	interrupts = <1 4 7>;
+	clocks = <&clk32k>;
+};
