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>;
|
||
|
};
