This allows LEDs to be controlled as a backlight device where they turn off and on when the display is blanked and unblanked. This is useful where you need various key backlight LEDs to dim at the same time as the backlight.

Say Y to enable Linux LED support. This allows control of supported
|
|
LEDs from both userspace and optionally, by kernel events (triggers).
|
|
|
|
This is not related to standard keyboard LEDs which are controlled
|
|
via the input system.

This driver makes the mail LED accessible from userspace

programs through the leds subsystem. This LED have three
|
|
known mode: off, blink at 0.5Hz and blink at 1Hz.
|
|
|
|
The driver supports two kinds of interface: using ledtrig-timer
|
|
or through /sys/class/leds/clevo::mail/brightness. As this LED
|
|
cannot change it's brightness it blinks instead. The brightness
|
|
value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
|
|
blink at 1Hz.
|
|
|

This module can drive the mail LED for the following notebooks:
|
|
