The LCD controller is composed of Frame Compression Processor (FCPVD), Video Signal Processor (VSPD), and Display Unit (DU). It has DPI/DSI interfaces and supports a maximum resolution of 1080p 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/G2L DU support for RZ/G2L alike SoCs.
