Use new signal routing capability for all comedi command *_src == TRIG_EXT options. This new interface allows the user specify signals and terminals as TRIG_EXT sources using a very consistent naming convention. Furthermore, the interface allows backwards compatibility to prior behavior of specifying register-level (or near register-level) values as *_arg options when *_src == TRIG_EXT. Annotates and updates tables of register values to reflect this new implementation status. Signed-off-by: Spencer E.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
