   298	 * struct xlnx_mix_layer_data - Describes the hardware configuration of a given
   299	 * mixer layer
   300	 * @hw_config: struct specifying the IP hardware constraints for this layer
   301	 * @vid_fmt: DRM format for this layer
   302	 * @can_alpha: Indicates that layer alpha is enabled for this layer
   303	 * @can_scale: Indicates that layer scaling is enabled for this layer
   304	 * @is_streaming: Indicates layer is not using mixer DMA but streaming from
   305	 *  external DMA
   306	 * @max_width: Max possible pixel width
   307	 * @max_height: Max possible pixel height
   308	 * @min_width: Min possible pixel width
   309	 * @min_height: Min possible pixel height
   310	 * @layer_regs: struct containing current cached register values
   311	 * @buff_addr: Current physical address of image buffer
   312	 * @x_pos: Current CRTC x offset
   313	 * @y_pos: Current CRTC y offset
   314	 * @width: Current width in pixels
   315	 * @height: Current hight in pixels
   316	 * @stride: Current stride (when Mixer is performing DMA)
   317	 * @alpha: Current alpha setting
   318	 * @is_active: Logical flag indicating layer in use.  If false, calls to
   319	 *  enable layer will be ignored.
   320	 * @scale_fact: Current scaling factor applied to layer
   321	 * @id: The logical layer id identifies which layer this struct describes
   322	 *  (e.g. 0 = master, 1-15 = overlay).
   323	 *
   324	 * All mixer layers are reprsented by an instance of this struct:
   325	 * output streaming, overlay, logo.
   326	 * Current layer-specific register state is stored in the layer_regs struct.
   327	 * The hardware configuration is stored in struct hw_config.
   328	 *
   329	 * Note:
   330	 * Some properties of the logo layer are unique and not described in this
   331	 * struct.  Those properites are part of the xlnx_mix struct as global
   332	 * properties.
