We'd like panels to be able to add things to debugfs underneath the connector's directory. Let's plumb it through. A panel will be able to put things in a "panel" directory under the connector's directory. Note that debugfs is not ABI and so it's always possible that the location that the panel gets for its debugfs could change in the future. NOTE: this currently only works if you're using a modern architecture. Specifically the plumbing relies on _both_ drm_bridge_connector and drm_panel_bridge. If you're not using one or both of these things then things won't be plumbed through. As a side effect of this change, drm_bridges can also get callbacks to put stuff underneath the connector's debugfs directory. At the moment all bridges in the chain have their debugfs_init() called with the connector's root directory.

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.
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.
