+* ARC HS Performance Counters
+
+The ARC HS 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 up to 32 counters.
+It also supports overflow interrupts.
+
+Required properties:

+- compatible : should contain
+	"snps,archs-pct"
+
+Example:
+
+pmu {
+        compatible = "snps,archs-pct";
+};

+* 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 up to 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

+Example:

+pmu {
+        compatible = "snps,arc700-pct";
