The ADV7180 and ADV7182 transmit whole fields, bottom field followed by top (or vice-versa, depending on detected video standard). So for chips that do not have support for explicitly setting the field mode via I2P, set the field mode to V4L2_FIELD_ALTERNATE. I2P converts fields into frames using an edge adaptive algorithm. The frame rate is the same as the 'field rate': e.g. X fields per second are now X frames per second.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
