Split-off DisplayPort functions from KMS helper library and move them
into their own module. Reduces the size of drm_kms_helper.ko by ~50%.

This patchset is part of an on-going effort to reduce the minimum
binary size of the DRM core and helpers. It's helpful for systems with
early-boot DRM graphics, which requires DRM to be linked into the
kernel image.

v2:
	* move helper library into subdirectory (Jani)
	* also move DP AUX bus helpers

Thomas Zimmermann (5):
  drm/dp_mst: Remove trailing whitespace.
  drm/dp: Move DP declarations into separate header file
  drm/dp: Move DisplayPort helpers into separate helper module
  drm/dp: Move public DisplayPort headers into dp/
  drm/dp: Move DisplayPort AUX bus helpers into dp/
