Shared support code inside the kernel's Direct Rendering Manager graphics stack that implements common display-protocol logic such as DisplayPort, HDMI, HDCP, and DSC handling. It is used by many GPU drivers rather than driving any particular piece of hardware itself.
This is not a hardware driver at all; it is a collection of helper routines that real GPU drivers link against to handle standard display interfaces. There is nothing to keep or remove here on hardware-support grounds, and the subtree is foundational to essentially every modern graphics driver in the tree.

Not a driver directory: generic DRM display support/helpers subtree, not a hardware-specific kernel driver for a chipset or device family.
