Hello, Here's the second version of the Renesas R-Car Display Unit (DU) DRM driver. 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, all eight planes and all hardware supported formats except 8-bit indexed color mode 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. Both the VGA and the LVDS outputs have been tested. Platform data are subject to change with the common display framework. This is why I haven't implemented DT bindings yet. Changes since v1: - Use drm_encoder_cleanup() directly as .destroy handlers - Enable alpha blending support - Don't re-reserve hardware plane at each update - Fix planes allocation for multiplanar formats - Add DRM PRIME support - Fix race condition between page flip request and handler - Add configurable z-order support for planes - Support configurable color keying for planes - Update plane format after releasing hardware planes - Fix register access for global registers - Fix plane index wrap-around for multi-planar overlays Please note that this version depends on the GEM CMA DRM PRIME patches I have previously sent to the dri-devel mailing list. I've included necessary arch/ modifications to allow easy testing. The r8a7779 clock patch should already be on its way to mainline, the Marzen board code will be resubmitted separately through the ARM tree after the DU driver gets pulled in the DRM tree.
