+description:
+ MediaTek PADDING provides ability to VDOSYS1 to fill pixels to
+ width and height of a layer with a specified color.
+ Since MIXER in VDOSYS1 requires the 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 the registers must be cleared to 0, otherwise
+ undeinfed behaviors could happen.
