Add an abstraction for the INTERFACE and CROP parts of the different Rockchip Camera Interface (CIF) variants. These parts are represented as V4L2 subdevice with one sink pad and one source pad. The sink pad is connected to a subdevice: either the subdevice provided by the driver of the companion chip connected to the DVP, or the subdevice provided by the MIPI CSI-2 receiver. The source pad is connected to V4l2 device(s) provided by one or many instance(s) of the DMA abstraction.

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 reStructuredText 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.
