Yes, it's good for me:
Acked-by: Nicolas Ferre <nicolas.ferre at atmel.com>

Thanks, bye,

> +Atmel AT91SAM9260 Real Time Timer
> +
> +Required properties:
> +- compatible: should be: "atmel,at91sam9260-rtt"
> +- reg: should encode the memory region of the RTT controller
> +- interrupts: rtt 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 time base when the RTT is used as an RTC.
> +	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).
