This series defines new formats and adds a plane property to be used for
floating point framebuffer content. Implementation is then added to i915.

I have shared an IGT branch which adds test coverage for the new formats:

  drm/fourcc: Add 64 bpp half float formats
  drm: Add optional PIXEL_NORMALIZE_RANGE property to drm_plane
  drm/i915: Implement half float formats and pixel normalize property
