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

  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
