The VI peripheral of Tegra supports capturing from MIPI CSI-2 or parallel video (called VIP in the docs). The staging tegra-video driver currently implements MIPI CSI-2 video capture for Tegra210. Add support for parallel video capture (VIP) on Tegra20. With the generalizations added to the VI driver in previous commits, this is only a matter of adding the vip.c and tegra20.c implementations and registering them. Unfortunately there was no documentation available for the VI or VIP peripherals of Tegra20 (or any other Tegra chips). This implementation has been based entirely on the code from a vendor kernel based on Linux 3.1 and massively adapted to fit into the tegra-video driver. Parts of this code is definitely non-optimal to say the least (especially tegra20_vi_enable() and the single-frame capture logic), but it was impossible to improve it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
