AMD Display Core link hardware sequencer helpers

An internal subdirectory of AMD's Display Core (DC) code inside the amdgpu graphics stack, containing helper routines that drive the link-layer hardware sequences (training, encoding, signal handling) used when amdgpu programs DisplayPort and HDMI outputs on Radeon and Ryzen integrated GPUs.

recommendation

This is not actually a standalone driver; it is a collection of internal helper files that form part of the larger amdgpu/DC display driver. It has no device binding of its own and is only meaningful as a building block of the AMD GPU driver, so it cannot be evaluated for keep-or-remove on its own terms.

codex reasoning notes (technical)

Not a driver directory: internal AMD DC display link/hwss helper code inside the amdgpu DRM stack, not a standalone kernel-bound hardware driver with its own device binding/entry point.
