    +description:
    + StarFive's JH8100 StarLink PMU integrates one or more CPU cores with a
    + shared L3 memory system. The PMU support overflow interrupt, up to
    + 16 programmable 64bit event counters, and an independent 64bit cycle
    + counter. StarFive's JH8100 StarLink PMU is accessed via MMIO.
