Instantiate a single LED based on the "led" subnode in DT. This allows the user to control display brightness and blinking (backed by hardware support) through the LED class API and triggers, and exposes the display color. The LED will be named "auxdisplay:<color>:<function>". When running in dot-matrix mode and if no "led" subnode is found, the driver falls back to the traditional backlight mode, to preserve backwards compatibility.

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.
