[Intel-gfx] [PATCH 0/4] Adding support for plane alpha/color blending through drm property

[sagar.a.kamble at intel.com]

From: Sagar Kamble <sagar.a.kamble at intel.com>

This patch series introduces drm property modelled after glBlendFuc function. For i915
constant alpha is exposed through this property to start with. Additional new property
value for controlling pre-multiplied alpha is added.
i-g-t test case is to be added.

These patches are based on following patches which are already under review/reviewed:

4ae74f3 Documentation: drm: describing drm properties exposed by various drivers
134bdfe Propagate the error from intel_update_plane() up through intel_plane_restore() to the caller.
a6ad21c Make drm_property_create_bitmask() a bit more generic by allowing the caller to specify which bits are in fact supported.

  drm: Added plane alpha and color blending property
  drm/i915: Enabling constant alpha drm property
  drm/i915: Enabling pre-multiplied alpha drm property
