Tegra194 contains a fourth display controller that does not own any windows. Therefore, we cannot currently assign a primary plane to it which causes KMS to eventually crash. Do not register the display controller if it owns no windows to work around this. Note that we still have to enable and probe the display controller because for some reason all display controllers need to be powered (and/or clocked) before any registers can be accessed in any of the display controllers.

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.
