The WAGO PFC controllers use a dedicated M4 remote processor to manage RGB LED strips. Communication with the M4 core is handled via a binary RPMsg protocol. A specialized wrapper is required to translate standard Linux LED class and pattern trigger events into RPMsg commands understood by the remote processor firmware. Support includes device tree based LED naming, initial default intensity configuration, and dynamic RGB pattern triggers. The driver registers LED devices at probe time for immediate trigger availability and polls the remote processor to minimize boot delays. An optional sysfs passthrough mechanism allows direct command execution for advanced diagnostics. Signed-off-by: Heinrich Toews <ht@twx-software.de>
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.
