INAGAKI Hiroshi 77b9f2d6fd dt-bindings: leds: Add LED_FUNCTION_SPEED_* for link speed on LAN/WAN
Add LED_FUNCTION_SPEED_LAN and LED_FUNCTION_SPEED_WAN for LEDs that
indicate link speed of ethernet ports on LAN/WAN. This is useful to
distinguish those LEDs from LEDs that indicate link status (up/down).

example:

Fortinet FortiGate 30E/50E have LEDs that indicate link speed on each
of the ethernet ports in addition to LEDs that indicate link status
(up/down).

- 1000 Mbps: green:speed-(lan|wan)-N
-  100 Mbps: amber:speed-(lan|wan)-N
-   10 Mbps: (none, turned off)

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.
