| 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>; |
| }; |
