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