The DU module supports the following hardware features − Display Parallel Interface (DPI) and MIPI LINK Video Interface − Display timing master − Generates video timings − Selecting the polarity of output DCLK, HSYNC, VSYNC, and DE − Supports Progressive − Input data format (from VSPD): RGB888, RGB666 − Output data format: same as Input data format − Supporting Full HD (1920 pixels x 1080 lines) for MIPI-DSI Output − Supporting WXGA (1280 pixels x 800 lines) for Parallel Output This patch document DU module found on RZ/G2L LCDC.
