The RZ/G3E Soc has 2 LCD controller (LCDC), contain a Frame Compression Processor (FCPVD), a Video Signal Processor (VSPD), Video Signal Processor (VSPD), and Display Unit (DU). - LCDC0 supports DSI and LVDS (single or dual-channel) outputs. - LCDC1 supports DSI, LVDS (single-channel), and RGB outputs. Add then two new SoC-specific compatible strings 'renesas,r9a09g047-du0' and 'renesas,r9a09g047-du1'.
