+description: |
+  Core Hang Detection provides the three sysfs entries for configuring
+  threshold, PMU event mux select and to enable hang detection.
+
+  If core is hung for threshold time (value X 10ns) and no
+  heart beat event from pmu to core hang monitor detection, core hang
+  interrupt would be generated to reset the SOC via secure watchdog
+  to collect all cores context.
+
+  PMU event mux select can be programmed to one of the supported
+  events, for example-
+  1) Load Instruction executed,
+  2) Store Instructions executed
+  3) Instruction architecturally executed and etc.
+
+  Writing 1 into enable sysfs entry, enables core hang detection and
+  if there is no selected PMU mux event for 10ns core hang counter
+  gets incremented. Once counter reaches the programmed threshold value,
+  core hang interrupts generated to reset the SOC.
