Atmel AT91SAM9260 Real Time Timer
Required properties:
-- compatible: should be: "atmel,at91sam9260-rtt"
+- compatible: should be one of the following:
+ - "atmel,at91sam9260-rtt"
+ - "microchip,sam9x60-rtt", "atmel,at91sam9260-rtt"
- reg: should encode the memory region of the RTT controller
- interrupts: rtt alarm/event interrupt
- clocks: should contain the 32 KHz slow clk that will drive the RTT block.
