    +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>;
    +};
