+
+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>;
