+* ARM architected timer
+
+ARM Cortex-A7 and Cortex-A15 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 "arm,armv7-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>;
+ };
