The following series of patches add writeback support for i915. This has been 
validated on TGL using IGT.

Note:Only a single instance of WD transcoder is being considered for now, using
multiple WD transcoder may not work. The support for the same will be added in next
set of patches.

suraj kandpal (4):
  drm: add writeback pointers to drm_connector
  drm/komeda: change driver to use drm_writeback_connector.base pointer
  drm/i915: Define WD trancoder for i915
  drm/i915: Enabling WD Transcoder
