Christian Marangi says: ==================== net: Add basic LED support for switch/phy This is a continue of [1]. It was decided to take a more gradual approach to implement LEDs support for switch and phy starting with basic support and then implementing the hw control part when we have all the prereq done. This series implements only the brightness_set() and blink_set() ops. An example of switch implementation is done with qca8k. For PHY a more generic approach is used with implementing the LED support in PHY core and with the user (in this case marvell) adding all the required functions. Currently we set the default-state as "keep" to not change the default configuration of the declared LEDs since almost every switch have a default configuration.

README
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.
