Currently the documentation for the arch_timer devicetree binding only lists "arm,armv7-timer". Add "arm,armv8-timer" to the list of compatible strings.

* 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>;
|
|
};
