drivers/bus

Linux bus controller subsystem directory

A top-level kernel source directory that gathers many unrelated on-chip bus controller drivers — the small interconnects that tie CPU cores to peripherals on SoCs and embedded boards. It is an organisational umbrella rather than a single piece of hardware.

recommendation

This is not actually a driver directory; it is a container holding dozens of independent bus controller drivers from different vendors and architectures. Any keep-or-remove decision has to be made on each child driver individually, not on the directory as a whole.

codex reasoning notes (technical)

Not a driver directory: top-level subsystem directory containing multiple unrelated bus driver implementations, not one specific hardware driver.
