The shared infrastructure the Linux kernel uses to discover and assign resources (IRQs, DMA channels, I/O ports, memory ranges) to Plug and Play devices, covering ISA PnP cards, PNPBIOS, and the ACPI-based enumeration used by modern PCs to describe motherboard devices like serial ports, embedded controllers, and legacy peripherals.
This is not actually a driver directory; it is the kernel's Plug and Play core, providing the enumeration and resource-allocation framework that other drivers build on top of. As infrastructure rather than a device driver, it falls outside the scope of the deprecation review.

codex reasoning notes (technical)
Not a driver directory: contains the Linux PnP core / enumeration and resource-management subsystem code (ACPI/BIOS/PNPACPI/ISAPnP plumbing), not a single kernel-bound hardware driver for a device family.
