+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";
+};
