+Atmel AT91SAM9260 Real Time Timer
+
+Required properties:
+- compatible: should be: "atmel,at91sam9260-rtt"
+- reg: should encode the memory region of the RTT controller
+- interrupts: rtc alarm/event interrupt
+- clocks: should contain one clock pointing the the slow clk
+- atmel,rtt-rtc-time-reg: should encode the GPBR register used to store
+ the RTC time. The first cell should point to the GPBR node and
+ the second one encode the offset within the GPBR block (or in
+ other words, the GPBR register used to store the current time
+ value).
+
+
+Example:
+
+rtt@fffffe00 {
+ compatible = "atmel,at91sam9260-rtt";
+ reg = <0xfffffd20 0x10>;
+ interrupts = <1 4 7>;
+ clocks = <&clk32k>;
+ atmel,rtt-rtc-time-reg = <&gpbr 0x0>;
+};
