+description:
+ Padding provides ability to add pixels to width and height of a layer with
+ specified colors. Due to hardware design, Mixer in VDOSYS1 requires
+ width of a layer to be 2-pixel-align, or 4-pixel-align when ETHDR is enabled,
+ we need Padding to deal with odd width.
+ Please notice that even if the Padding is in bypass mode, settings in
+ register must be cleared to 0, or undefined behaviors could happen.
