Is there a review for a dmc620 driver still to come?

lib/libpmc/libpmc.c

1370

Missing break?

sys/arm64/include/cmn600_reg.h

30–31

sys/dev/hwpmc/pmc_events.h

2065–2067

Is there a possibility that future revisions of this hw will add more events to any of these lists? Should these ranges be spaced out further to accommodate this?

sys/dev/hwpmc/pmu_dmc620_reg.h

77–81

This struct should go in sys/dev/hwpmc/hwpmc_dmc620.h.
