[PATCH v3 0/4] perf: ampere: Add support for Ampere SoC PMUs

[Ilkka Koskinen]

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

  perf: arm_cspmu: Split 64-bit write to 32-bit writes
  perf: arm_cspmu: Support implementation specific filters

  perf: arm_cspmu: ampere_cspmu: Add support for Ampere SoC PMU
