Add a new trigger which turns LEDs on when there is input (/dev/input/event*) activity and turns them back off again after there has been no activity for 5 seconds. This is primarily intended to control LED devices which are a backlight for capacitive touch-buttons, such as e.g. the menu / home / back buttons found on the bottom bezel of many somewhat older smartphones and tablets. This can also be used to turn on the keyboard backlight LED on input events and turn the keyboard backlight off again when idle.

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 reStructuredText 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.
