Subject: [PATCH v2 0/5] perf: ampere: Add support for Ampere SoC PMUs

Changes since v1:
    * Rather than creating a completely new driver, implemented as a submodule
      of Arm CoreSight PMU driver
    * Fixed shared filter handling


Ilkka Koskinen (5):
  perf: arm_cspmu: Support 32-bit accesses to 64-bit registers
  perf: arm_cspmu: Support shared interrupts
  perf: arm_cspmu: Support implementation specific filters
  perf: arm_cspmu: Support implementation specific event validation
  perf: arm_cspmu: ampere_cspmu: Add support for Ampere SoC PMU
