drm/dp: Move DisplayPort helpers into separate helper module
Move DisplayPort functions into a separate module to reduce the size of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c This change can help to reduce the size of the kernel binary. Some numbers from a x86-64 test build: Before: drm_kms_helper.ko: 447480 bytes After: drm_dp_helper.ko: 216632 bytes drm_kms_helper.ko: 239424 bytes For early-boot graphics, generic DRM drivers, such as simpledrm, require DRM KMS helpers to be built into the kernel. Generic helper functions for DisplayPort take up a significant portion of DRM KMS helper library. These functions are not used by generic drivers and can be loaded as a module. v3: * fix include statement in DRM selftests v2: * move DP helper code into dp/ (Jani) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Lyude Paul <lyude@redhat.com> Acked-by: Daniel Vetter <daniel@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220114114535.29157-4-tzimmermann@suse.de
