| 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 the 32 KHz slow clk that will drive the RTT block. | |
| - 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 time base). | |
| Example: | |
| rtt@fffffd20 { | |
| compatible = "atmel,at91sam9260-rtt"; | |
| reg = <0xfffffd20 0x10>; | |
| interrupts = <1 4 7>; | |
| clocks = <&clk32k>; | |
| atmel,rtt-rtc-time-reg = <&gpbr 0x0>; | |
| }; |
