What: /sys/class/leds/<led>/device/brightness

Description: (RW) On the front panel of the Turris Omnia router there is also
|
|
a button which can be used to control the intensity of all the
|
|
LEDs at once, so that if they are too bright, user can dim them.
|
|
|
|
The microcontroller cycles between 8 levels of this global
|
|
brightness (from 100% to 0%), but this setting can have any
|
|
integer value between 0 and 100. It is therefore convenient to be
|
|
able to change this setting from software.

KernelVersion: 6.6

|
Description: (RW) Newer versions of the microcontroller firmware of the
|
|
Turris Omnia router support gamma correction for the RGB LEDs.
|
|
This feature can be enabled/disabled by writing to this file.
|
|
|
|
If the feature is not supported because the MCU firmware is too
|
|
old, the file always reads as 0, and writing to the file results
|
|
in the EOPNOTSUPP error.
