drm/i915: Add explicit pipe src size to pipe config
Rather that mess about with hdisplay/vdisplay from requested_mode, add explicit pipe src size information to pipe config. Now requested_mode is only really relevant for dvo/sdvo output timings. For everything else either adjusted_mode or pipe src size should be used. In many places where we end up using pipe source size, we should actually use the primary plane size, but we don't currently store that information explicitly. As long as we treat primaries as full screen only, we can get away with this. Eventually when we move primaries over to drm_plane, we need to fix it all up. v2: Add a comment to explain what pipe_src_{w,h} are Add a note about primary planes to commit message Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
