Hello, Here's a driver for the VSP1 (Video Signal Processor) engine found in several Renesas R-Car SoCs. The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way, making this driver a prime candidate for the media controller API. Due to the configurable nature of the pipeline the driver doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage. The patch series starts with a fix for the media controller graph traversal code, a documentation fix and new pixel format and media bus code definitions. The last patch finally adds the VSP1 driver.
