+* 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
+ "snps,arc700-pct"
+
+Example:
+
+pmu {
+ compatible = "snps,arc700-pct";
+};
