Subject: [PATCH v2 0/8] drivers/perf: hisi_pcie: Several updates for HiSilicon PCIe PMU driver

From: Yicong Yang <yangyicong@...ilicon.com>

This series mainly fix and optimize the several usage of the driver:
- Add more events to complement the TLP bandwidth counting
- Fix the wrong counting on using the event group
- Properly check the target filter to avoid invalid filter value
- Optimize the handling of related events which are not in an event group
- Update the docs

Change since v1:
- Rename hisi_pcie_pmu_{config,clear}_filter() to properly reflect its function.
- Add some test case logs to the Patch 5/8 comments.
- Avoid use HISI_PCIE_MAX_COUNTER outside of functions in Patch 7/8.
