[PATCH 0/6] Add PPMU support for Tesla FSD

[Vivek Yadav]

The Platform Performance Measuring Unit (PPMU) is an AMBA-compliant
performance measurement tool designed to provide observability into
system-level operations. It provides performance statistics such as
as bandwidth, read and write request, transactions count for AXI masters.

FSD platform has two instances of PPMU IP in MFC. This patch series
contains PPMU clock binding definitions, device tree binding
documentation, PPMU24 driver support which configures the
PPMU24 hardware and the PPMU device tree node support
for Tesla FSD platform.

Vivek Yadav (6):
  dt-bindings: clock: Add PPMU clock definitions for FSD platform
  clk: samsung: fsd: Use clock IDs for PPMU MFC block
  dt-bindings: perf: Add devicetree binding for custom PPMU
  drivers: perf: samsung: Add PPMU driver support
  arm64: dts: fsd: Add PPMU support for MFC block of FSD SoC
  MAINTAINERS: Add maintainers for Samsung PPMU driver
