+* 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";

+freeze_processes() (defined in kernel/power/process.c) is called.  A system-wide

 __refrigerator() must not be called directly.  Instead, use the
