From: Yicong Yang <yangyicong@hisilicon.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC0GTV ---------------------------------------------------------------------- The HiSilicon Uncore PMU framework implements some common functions and exported them to the drivers. Use a specific HISI_PMU namespace for the exported symbols to avoid pollute the generic ones.
