- 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>;
- };
