Changes since v6:
* Rebased on top of Besar's updated patch
[PATCH v6] perf: arm_cspmu: Separate Arm and vendor module
https://lore.kernel.org/all/20230821231608.50911-1-bwicaksono@xxxxxxxxxx/
* Changed Ampere specific module to use ida/ida_alloc() instead of idr/idr_alloc()
Changes since v5:

* Rebased on top of Besar's patch
[PATCH v5] perf: arm_cspmu: Separate Arm and vendor module
https://lore.kernel.org/all/20230705104745.52255-1-bwicaksono@xxxxxxxxxx/
* v5: https://lore.kernel.org/all/20230714010141.824226-1-ilkka@xxxxxxxxxxxxxxxxxxxxxx/
Changes since v4:
* "Support implementation specific filters" patch:
- Added comment about filter and impdef registers and reference
to the Coresight PMU specification to the commit message
* "Add support for Ampere SoC PMU" patch:
- Fixed the documentation and added more comments
- Changed the incrementing PMU index number to idr_alloc()
(Needs a impdef release hook patch to release unused index)
- Fixed style in init_ops() to more reasonable
- Moved bank parameter to config1
Changes since v3:
* use_64b_counter_reg => has_atomic_dword (patch 1/4)
* Removed the unnecessary hook for group validation (patch 3/4)
* Added group config validation to ampere_cspmu_validate_event() (patch 4/4)
* Rebased the patchset
Changes since v2:
* Changed to use supports_64bits_atomics() and replaced the split writes
with lo_hi_writeq()
* Added implementation specific group validation to patch 3
* Dropped shared interrupt patch
* Removed unnecessary filter_enable parameter from ampere module
* Added group validation to ampere module
Changes since v1:
* Rather than creating a completely new driver, implemented as a submodule
of Arm CoreSight PMU driver
* Fixed shared filter handling
