This path series aims to add support for RZ/G2L DU DRM driver. RZ/G2L LCD controller composed of Frame compression Processor(FCPVD), Video signal processor (VSPD) and Display unit(DU). The output of LCDC is connected to Display parallel interface and MIPI link video interface. The output from DSI is connected to ADV7535.

ditr5 based on latest HW manual 1.3.0/1.4.0 * Updated the comment for auto clear. * Replaced writel()->rzg2l_du_write() in rzg2l_du_start_stop(). * Dropped CRC related functions as it does not have

series. * Added Rb tag from Laurent for the binding patch. * Updated the commit description. * Updated description of the port by dropping the text "specified in
