Hello, Here's a new DRM driver for the Renesas R-Car Display Unit (DU). The DU features two superposition processors (modeled as CRTCs) and eight planes that can be shared between the superposition processors. The driver supports the superposition processors (currently in pure overlay mode without alpha blending), all eight planes and all hardware supported formats except 8-bit indexed color more and 32-bit RGB666 mode (that would be [31:0] x:R:x:G:x:B:x 8:6:2:6:2:6:2 little endian, not supported by DRM at the moment). On the output side only sync master non-interlaced modes are currently supported. Only the VGA output has been tested, as I lack an LVDS panel for the development board. The second CRTC hasn't been tested for the same reason. Platform data are subject to change with the common display framework. This is why I haven't implemented DT bindings yet.
