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.
See also /sys/class/backlight/<backlight>/ambient_light_level and
/sys/class/backlight/<backlight>/ambient_light_zone.

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.
