* 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";
};
