The LCD controller is composed of Frame Compression Processor (FCPVD), Video Signal Processor (VSPD), and Display Unit (DU). It has DPI interface and supports a maximum resolution of WXGA along with 2 RPFs to support the blending of two picture layers and raster operations (ROPs). The DU module is connected to VSPD. Add RZ/G2UL DU support.
