This patchset adds support for HiSilicon PCIe Performance Monitoring Unit(PMU). It is a PCIe Root Complex integrated End Point(RCiEP) device added on Hip09. Each PCIe Core has a PMU RCiEP to monitor multi root ports and all Endpoints downstream these root ports. HiSilicon PCIe PMU is supported to collect performance data of PCIe bus, such as: bandwidth, latency etc. This patchset is based on 5.12-rc6. Changes since v2: - Address the comments from John. - Link: https://lore.kernel.org/linux-arm-kernel/1617959157-22956... Changes since v1: - Drop the internal Reviewed-by tag. - Fix some build warnings when W=1. - Link: https://lore.kernel.org/linux-arm-kernel/1617788943-52722...
