3NDS32 core have a PMU for counting cpu and cache events like cache misses.
4The NDS32 PMU representation in the device tree should be done as under:

6Required properties:
7
8- compatible :
9	"andestech,nds32v3-pmu"
10
11- interrupts : The interrupt number for NDS32 PMU is 13.

14pmu{
15	compatible = "andestech,nds32v3-pmu";
16	interrupts = <13>;
