/**
 * struct mdp_overlay - overlay surface structure
 * @src:	Source image information (width, height, format).
 * @src_rect:	Source crop rectangle, portion of image that will be fetched.
 *		This should always be within boundaries of source image.
 * @dst_rect:	Destination rectangle, the position and size of image on screen.
 *		This should always be within panel boundaries.
 * @z_order:	Blending stage to occupy in display, if multiple layers are
 *		present, highest z_order usually means the top most visible
 *		layer. The range acceptable is from 0-3 to support blending
 *		up to 4 layers.
 * @is_fg:	This flag is used to disable blending of any layers with z_order
 *		less than this overlay. It means that any layers with z_order
 *		less than this layer will not be blended and will be replaced
 *		by the background border color.
 * @alpha:	Used to set plane opacity. The range can be from 0-255, where
 *		0 means completely transparent and 255 means fully opaque.
 * @transp_mask: Color used as color key for transparency. Any pixel in fetched
 *		image matching this color will be transparent when blending.
 *		The color should be in same format as the source image format.
 * @flags:	This is used to customize operation of overlay. See MDP flags
 *		for more information.
 * @user_data:	DEPRECATED* Used to store user application specific information.
 * @bg_color:	Solid color used to fill the overlay surface when no source
 *		buffer is provided.
 * @horz_deci:	Horizontal decimation value, this indicates the amount of pixels
 *		dropped for each pixel that is fetched from a line. The value
 *		given should be power of two of decimation amount.
 *		0: no decimation
 *		1: decimate by 2 (drop 1 pixel for each pixel fetched)
 *		2: decimate by 4 (drop 3 pixels for each pixel fetched)
 *		3: decimate by 8 (drop 7 pixels for each pixel fetched)
 *		4: decimate by 16 (drop 15 pixels for each pixel fetched)
 * @vert_deci:	Vertical decimation value, this indicates the amount of lines
 *		dropped for each line that is fetched from overlay. The value
 *		given should be power of two of decimation amount.
 *		0: no decimation
 *		1: decimation by 2 (drop 1 line for each line fetched)
 *		2: decimation by 4 (drop 3 lines for each line fetched)
 *		3: decimation by 8 (drop 7 lines for each line fetched)
 *		4: decimation by 16 (drop 15 lines for each line fetched)
 * @overlay_pp_cfg: Overlay post processing configuration, for more information
 *		see struct mdp_overlay_pp_params.
