The adv748x-csi2 driver configures the CSI-2 transmitter to automatically infer the image stream format from the connected frontend (HDMI or AFE). Setting a new format on the subdevice hence does not actually control the CSI-2 output format, but it's only there for the purpose of pipeline validation. However, there is currently no validation that the supplied media bus code is valid and supported by the device. With the introduction of enum_mbus_codes a list of supported format is now available, use it to validate that the supplied format is correct and use the default UYVY8 one if that's not the case.

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.
