From: RafaÅ MiÅecki
Date: Thu Aug 25 2016 - 05:54:53 EST


From: RafaÅ MiÅecki <rafal@xxxxxxxxxx>

Documentation of sysfs interface should be in ABI in the first place.
This moves relevant part of documentation and mentions where to look for
it.

of led events.
You can change triggers in a similar manner to the way an IO
scheduler is chosen. Trigger specific parameters can appear in
- /sys/class/leds/<led> once a given trigger is selected.
+ /sys/class/leds/<led> once a given trigger is selected. For
+ their documentation see sysfs-class-led-trigger-*.

-This adds the following sysfs attributes to the LED:
-
- delay_on - specifies for how many milliseconds the LED has to stay at
- LED_FULL brightness after it has been armed.
- Default to 100 ms.
-
- delay_off - specifies for how many milliseconds the LED has to stay at
- LED_OFF brightness after it has been armed.

- invert - reverse the blink logic. If set to 0 (default) blink on for delay_on
