This patch adds support to capture from the external sensor based on device graph in the device tree. Driver walks through the device graph to create media links between the entities and registers and unregisters video devices when the corresponding sub-devices are bound and unbound. Channel formats are enumerated based on available formats from the sensor and the corresponding matched formats from the Tegra supported video formats list. Each Tegra CSI instance can be configured as 4-lane or 2-lane based on supported lane configuration from the sensor through the device tree. Currently this driver supports V4L2 video node centric only.

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.
