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:
|
|
|
|
Clevo D400P
|
|
Clevo D410J
|
|
Clevo D410V
|
|
Clevo D400V/D470V (not tested, but might work)
