[PATCH v5 0/2] perf: Fujitsu: Add Uncore MAC/PCI PMU driver

[Koichi Okuno]

This adds two new dynamic PMUs to the Perf Events framework to program
and control the Uncore MAC/PCI PMUs in Fujitsu chips.

These drivers were created with reference to drivers/perf/qcom_l3_pmu.c.

These drivers export formatting and event information to sysfs so they can
be used by the perf user space tools with the syntaxes:

perf stat -e mac_iod0_mac0_ch0/ea-mac/ ls
perf stat -e mac_iod0_mac0_ch0/event=0x80/ ls

perf stat -e pci_iod0_pci0/ea-pci/ ls
perf stat -e pci_iod0_pci0/event=0x80/ ls

FUJITSU-MONAKA PMU Events Specification v1.1 URL:
https://github.com/fujitsu/FUJITSU-MONAKA

Changes in v5:
- Update PMU events for FUJITSU-MONAKA to latest(v1.1) spec.
  The changed events are as follows:
  - Removed events:
    ea-memory-mac-read
    ea-memory-mac-pwrite
  - Description changed events:
    read-count-return
    read-count-return-pftgt-hit
    read-count-return-pftgt-miss
    ea-mac
    ea-memory
    ea-ha
    ea-pci
- Modify the code as suggested. (Jonathan Cameron)
  - Added include mod_devicetable.h.
  - EA events that share the same description as MAC events have been
    removed.
    These events will remain in the specification, but will be removed
    from the code.
    These events will be supported in future enhancements as the
    specification changes.
  - Changed MAC events with the same description to different
    description.
  - Changed some programming styles as suggested.
- Link to v4:https://lore.kernel.org/all/20250116045911.3382537-1-fj5100bi@fujitsu.com/
