        There are newer controls (V4L2_CID_PAN*, V4L2_CID_TILT*) that provide

+What:  V4L2 selections API target rectangle and flags unification, the
+       following definitions will be removed: V4L2_SEL_TGT_CROP_ACTIVE,
+       V4L2_SEL_TGT_COMPOSE_ACTIVE, V4L2_SUBDEV_SEL_*, V4L2_SUBDEV_SEL_FLAG_*
+       in favor of common V4L2_SEL_TGT_* and V4L2_SEL_FLAG_* definitions.
+       For more details see include/linux/v4l2-common.h.
+When:  3.8
+Why:   The regular V4L2 selections and the subdev selection API originally
+       defined distinct names for the target rectangles and flags - V4L2_SEL_*
+       and V4L2_SUBDEV_SEL_*. Although, it turned out that the meaning of these
+       target rectangles is virtually identical and the APIs were consolidated
+       to use single set of names - V4L2_SEL_*. This didn't involve any ABI
+       changes. Alias definitions were created for the original ones to avoid
+       any instabilities in the user space interface. After few cycles these
+       backward compatibility definitions will be removed.
