All of the formats/modifiers supported by the plane during synchronous
flips are nor supported by asynchronous flips. The formats/modifiers
exposed to user by IN_FORMATS exposes all formats/modifiers supported by
plane and this list varies for async flips. If the async flip supported
formats/modifiers are exposed to the user, user based on this list can
take decision to proceed or not and avoid flip failures during async
flips.
Discussion around this can be located @

Userspace implementation for IN_FORMARTS_ASYNC under review @

TODO: Upon merge of the patch related to async flip
https://patchwork.freedesktop.org/patch/626849/?series=139807&rev=6
the patch 5 in this series will have to make use of the new function
pointer can_async_flip().

v3: Add new plane->funcs format_mod_supported_async (Ville)
v4: reuse the existing can_async_flip in i915 (Ville)
    pass format_mod_supported/async as parameter to create_in_formats
    function & leave the modifiers/formats in drm_format_modifer_blob
    untouched (Ville)

Arun R Murthy (3):
  drm/plane: Add new plane property IN_FORMATS_ASYNC
  drm/plane: Expose function to create format/modifier blob
  drm/i915/display: Populate list of async supported formats/modifiers
