AMD DCN 2.1 Display Clock Generator Support Code

Internal helper code inside AMD's Display Core (DC) component that programs the clock generators on DCN 2.1 display engines, found in Renoir and Lucienne APUs (Ryzen 4000/5000 series mobile and desktop integrated graphics from around 2020).

recommendation

This is not actually a standalone driver; it is a sub-component of the larger amdgpu display stack that handles clock generation for one specific generation of AMD's display hardware. It lives or dies with the surrounding amdgpu driver and should not be evaluated on its own.

codex reasoning notes (technical)

Not a driver directory: contains AMD DC display clock-generator (DCCG/DCN2.1) internal display-pipeline support code, not a standalone kernel hardware driver.
