Hello, lo and behold, here's the sixth, latest, greatest and most amazing ever (so far) version of the Xilinx FPGA Video IP Cores kernel drivers. I won't detail in great lengths the Xilinx Video IP architecture here, as that would result in dozens of pages of documentation. The interested reader can refer to the Zynq ZC702 Base TRD (Targeted Reference Design) User Guide (http://www.xilinx.com/support/documentation/boards_and_kits/zc702_zvik/2014_2/ug925-zynq-zc702-base-trd.pdf). In a nutshell, the Xilinx Video IP Cores architecture specifies how video-related IP cores need to be designed to interoperate and how to assemble them in pipelines of various complexities. The concepts map neatly to the media controller architecture, which this patch set uses extensively. The series starts with various new V4L2 core features, bug fixes or cleanups, with a small documentation enhancement (1/8), the addition of new media bus formats needed by the new drivers (2/8 to 4/8) and a new V4L2 OF link parsing function (5/8). The last three patches are the core of this series. Patch 6/8 adds support for the Xilinx Video IP architecture core in the form of a base object to model video IP cores (xilinx-vip.c - Video IP), a framework that parses a DT representation of a video pipeline and connects the corresponding V4L2 subdevices together (xilinx-vipp.c - Video IP Pipeline) and a glue between the Video DMA engine driver and the V4L2 API (xilinx-dma.c). Patch 7/8 adds a driver for the Video Timing Controller (VTC) IP core. While not strictly a video processing IP core, the VTC is required by other video IP core drivers. Finally, patch 8/8 adds a first video IP core driver for the Test Pattern Generator (TPG). Drivers for other IP cores will be added in the future.
