* @formats: array of supported formats (%DRM_FORMAT_*)

*
* The plane hardware is used when the display scanout run into plane active
* scanout, that means we can reuse the plane hardware resources on plane
* non-active scanout.
*
* Because resource share, There are some limit on share plane: one group
* of share planes need use same zpos, can't not overlap, etc.
*
* Here assume share plane is a universal plane with some limit flags.
* people who use the share plane need know the limit, should call the ioctl
* DRM_CLIENT_CAP_SHARE_PLANES, and judge the planes limit before use it.
*
* Returns:
* Zero on success, error code on failure.
