[PATCH v2 0/8] perf: add NVIDIA Tegra410 Uncore PMU support

[Besar Wicaksono]

This series adds driver support for the following Uncore PMUs in
NVIDIA Tegra410 SoC:
  - Unified Coherence Fabric (UCF)
  - PCIE
  - PCIE-TGT
  - CPU Memory (CMEM) Latency
  - NVLink-C2C
  - NV-CLink
  - NV-DLink

Changes from v1:
  * Add more clarity on the commit message.
  * Fix build error reported by kernel test robot on PATCH 6/8.
    * It was missing ACPI dependency on Kconfig for the CPU Memory
      Latency PMU.
  * Apply code formatting suggestions from Ilkka.
  * Added Reviewed-by from Ilkka.
Thanks to Ilkka, Krzysztof, and Jon for the comments.
