Internal support code for the Audio Co-Processor block found on AMD APUs and GPUs. It is not a standalone driver but a set of helpers that the main amdgpu graphics driver uses to bring up and control the on-chip audio hardware.
This is not actually a driver directory; it is a sub-component of the amdgpu graphics stack that provides hardware-control glue for the Audio Co-Processor block. It builds only as part of amdgpu and does not register a device on its own, so it falls outside the scope of standalone driver review.

codex reasoning notes (technical)
Not a driver directory: Kconfig/Makefile identify it as an ACP sub-component wired into amdgpu, providing internal hardware-control glue rather than a standalone kernel-bound device driver.
