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.
