sysfs interface for analog devices adp8860 backlight driver
|
-----------------------------------------------------------
|
|
The backlight brightness control operates at three different levels for the
|
adp8860, adp8861 and adp8863 devices: daylight (level 1), office (level 2) and
|
dark (level 3). By default the brightness operates at the daylight brightness
|
level.

Description:
|
(RW) Maximum current setting for the backlight when brightness
|
is at one of the three levels (daylight, office or dark). This
|
is an input code between 0 and 127, which is transformed to a
|
value between 0 mA and 30 mA using linear or non-linear
|
algorithms.
