The TPG support registers a v4l2-subdev for this, but this is not part of the media-controller graph in any way. After manually selecting the TPG as input using the s_input ioctl it does not work. Several supported sensors have their own working TPG and using the sensor's TPG means that the same data-flow is used as with actual sensors rather then the quite different data-flow from the ISP's builtin TPG. Remove the broken TPG support, when a test-pattern is needed for testing a sensor's TPG can be used. Using a sensor's TPG is actually better for testing since then the actual normal data-flow is being tested.

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.
