+* ARC Performance Counters
+
+The ARC700 can be configured with a pipeline performance monitor for counting
+CPU and cache events like cache misses and hits. Like conventional PCT there
+are 100+ hardware conditions dynamically mapped to upto 32 counters
+
+Note that:
+ * The ARC 700 PCT does not support interrupts; although HW events may be
+   counted, the HW events themselves cannot serve as a trigger for a sample.
+
+Required properties:
+
+- compatible : should contain
+	"snps,arc700-pct"
+
+Example:
+
+pmu {
+        compatible = "snps,arc700-pct";
+};

-* ARC Performance Monitor Unit

-The ARC 700 can be configured with a pipeline performance monitor for counting
-CPU and cache events like cache misses and hits.
-
-Note that:
- * ARC 700 refers to a family of ARC processor cores;
-   - There is only one type of PMU available for the whole family;
-   - The PMU may support different sets of events; supported events are probed
-     at boot time, as required by the reference manual.
-
- * The ARC 700 PMU does not support interrupts; although HW events may be
-   counted, the HW events themselves cannot serve as a trigger for a sample.
-
-Required properties:
-
-- compatible : should contain
-	"snps,arc700-pmu"
-
-Example:
-
-pmu {
-        compatible = "snps,arc700-pmu";
-};
