AMD DCN 4.2 Display Clock Generator helpers
Internal helper code inside AMD's amdgpu display stack that programs the display clock generator block on DCN 4.2 generation GPUs. It is one small piece of the larger Display Core (DC) library used by modern Radeon and Ryzen integrated graphics, not a free-standing driver.
not-a-driver
recommendation
This is not actually a driver directory; it is a sub-component of the amdgpu DRM driver's Display Core library, providing clock generator support for the DCN 4.2 display IP. It only makes sense as part of the wider AMD display stack and is not independently loadable or removable.

codex reasoning notes (technical)
Not a driver directory: AMD DCN4.2 display clock generator helper code inside the amdgpu display stack, not a standalone kernel-bound hardware driver.
