[Intel-gfx] [PATCHv2 0/5] Support blending modes of display planes

[Vandita Kulkarni]

From: vandita kulkarni <vandita.kulkarni at intel.com>

The below patches support plane and pixel blending
by adding two properties blend_func and blend_color.
As per Damien's initial patches, this design based on 
OpenGL's blend equations is suggested by Ville.
All the below patches are tested on BXT android platform.

V2: Squashed all the blend color related patches to one
single patch and blend func related pathces into one single
patch.

The initial kernel patches from damien can be found at

  drm: Introduce the blend-func property
  drm/i915/skl: Add blend_func to SKL/BXT sprite planes
  drm: Introduce DRM_MODE_COLOR()

  drm/i915/skl: Add support for blending modes
