As with the Arm CMN family, there are already future NI products on the roadmap, so the overall binding is named generically just in case any non-discoverable incompatibility between generations crops up.

While this is technically discoverable by a careful driver that understands the part number in the peripheral ID registers (which do at least remain in the same place), a new unique compatible seems warranted to avoid any surprises.

Not to be confused with CoreSight debug and trace, the PMU architecture defines a standard MMIO interface for event counters following a similar design to the CPU PMU architecture, where the implementation and most of its features are discoverable through ID registers.
