This adds support for detecting this model board and registers some LEDs and buttons. There are two uncommon things regarding this device: 1) It can use two different "board_id" ID values. Unit I have uses "U12H139T00_NETGEAR" value. This magic is also used in firmware file header. There are two reports (one from an OpenWrt user) of a different "U12H139T50_NETGEAR" magic though. 2) Power LEDs share GPIOs with buttons. Amber one seems to share GPIO 2 with WPS button and green one seems to share GPIO 3 with reset button. It remains unknown how to support them and handle buttons at the same time. For that reason they aren't added to the list of supported LEDs.

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.
