Linux's "usbport" trigger is a bit specific one. It allows LED to follow state of multiple USB ports which have to be selected additionally (there isn't a single trigger for each port). Default list of USB ports to monitor can be specified using "trigger-sources" DT property. Theoretically it should be possible for Linux to deduce applicable trigger based on the references nodes in the "trigger-sources". It hasn't been implemented however (probably due to laziness). Milk spilled - we already have DT files specifying "usbport" manually - allow that value in the binding. This fixes validation of in-kernel and external DT files.

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.
