Hello,

Here's (finally) a set of kernel drivers to support the Xilinx FPGA Video IP
Cores architecture.

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 (01/11), the addition of new media bus
formats needed by the new drivers (02/11 to 04/11), a new V4L2 OF link parsing
function (05/11).

The next three patches (06/11 to 08/11) fix bugs in the Xilinx Video DMA
driver. They are required as a runtime dependency but will not break
compilation. They could thus be applied separately through the DMA engine tree
if needed. If that's required, and if time still permits, getting those
patches merged in v3.18 could help.

The last three patches are the code or this series.

Patch 09/11 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 10/11 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 11/11 adds a first video IP core driver for the Test Pattern
Generator (TPG). Drivers for other IP cores will be added in the future.
