sysfs interface for analog devices adp5520(01) backlight driver --------------------------------------------------------------- The backlight brightness control operates at three different levels for the adp5520 and adp5501 devices: daylight (level 1), office (level 2) and dark (level 3). By default the brightness operates at the daylight brightness level.

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.
