/**
* DOC: overview
*
* FB_DAMAGE_CLIPS is an optional plane property which provides a means to
* specify a list of damage rectangles on a plane in framebuffer coordinates of
* the framebuffer attached to the plane. In current context damage is the area
* of plane framebuffer that has changed since last plane update (also called
* page-flip), irrespective of whether currently attached framebuffer is same as
* framebuffer attached during last plane update or not.
*
* FB_DAMAGE_CLIPS is a hint to kernel which could be helpful for some drivers
* to optimize internally especially for virtual devices where each framebuffer
* change needs to be transmitted over network, usb, etc.
*
* Since FB_DAMAGE_CLIPS is a hint so it is an optional property. User-space can
* ignore damage clips property and in that case driver will do a full plane
* update. In case damage clips are provided then it is guaranteed that the area
* inside damage clips will be updated to plane. For efficiency driver can do
* full update or can update more than specified in damage clips. Since driver
* is free to read more, user-space must always render the entire visible
* framebuffer. Otherwise there can be corruptions. Also, if a user-space
* provides damage clips which doesn't encompass the actual damage to
* framebuffer (since last plane update) can result in incorrect rendering.
*
* FB_DAMAGE_CLIPS is a blob property with the layout of blob data is simply an
* array of &drm_mode_rect. Unlike plane &drm_plane_state.src coordinates,
* damage clips are not in 16.16 fixed point. Similar to plane src in
* framebuffer, damage clips cannot be negative. In damage clip, x1/y1 are
* inclusive and x2/y2 are exclusive. While kernel does not error for overlapped
* damage clips, it is strongly discouraged.
*
* Drivers that are interested in damage interface for plane should enable
* FB_DAMAGE_CLIPS property by calling drm_plane_enable_fb_damage_clips().
* Drivers implementing damage can use drm_atomic_helper_damage_iter_init() and
* drm_atomic_helper_damage_iter_next() helper iterator function to get damage
* rectangles clipped to &drm_plane_state.src.
