[PATCH 0/2] drm/sti: support of interlaced content with Bottom Field

Interlaced video can have different scan order:
Top Field First or Bottom Field First

In case of video with interlaced content, this information should be
propagated from the userland to the DRM kernel driver that will process the
deinterlacing starting with the top or the bottom field first.
That's why we introduce this new flag definition DRM_MODE_FB_BFF (Bottom Field
First) that should be used jointly with the already existing
DRM_MODE_FB_INTERLACED flag incase of interlaced video with Bottom Field First
scan order should be processed.
