- * ARM architected timer
- ARM cores may have a per-core architected timer, which provides per-cpu timers.
- The timer is attached to a GIC to deliver its per-processor interrupts.
- ** Timer node properties:
- - compatible : Should at least contain one of
- "arm,armv7-timer"
- "arm,armv8-timer"
- - interrupts : Interrupt list for secure, non-secure, virtual and
- hypervisor timers, in that order.
- - clock-frequency : The frequency of the main counter, in Hz. Optional.
- Example:
- timer {
- compatible = "arm,cortex-a15-timer",
- "arm,armv7-timer";
- interrupts = <1 13 0xf08>,
- <1 14 0xf08>,
- <1 11 0xf08>,
- <1 10 0xf08>;
- clock-frequency = <100000000>;
- };
