1* ARM architected timer
2
3ARM cores may have a per-core architected timer, which provides per-cpu timers.
4
5The timer is attached to a GIC to deliver its per-processor interrupts.
6
7** Timer node properties:
8
9- compatible : Should at least contain one of
10 "arm,armv7-timer"
11 "arm,armv8-timer"
12
13- interrupts : Interrupt list for secure, non-secure, virtual and
14 hypervisor timers, in that order.
15
16- clock-frequency : The frequency of the main counter, in Hz. Optional.
17
18Example:
19
20 timer {
21 compatible = "arm,cortex-a15-timer",
22 "arm,armv7-timer";
23 interrupts = <1 13 0xf08>,
24 <1 14 0xf08>,
25 <1 11 0xf08>,
26 <1 10 0xf08>;
27 clock-frequency = <100000000>;
28 };
