4 The backlight brightness control operates at three different levels for the
5 adp5520 and adp5501 devices: daylight (level 1), office (level 2) and dark
6 (level 3). By default the brightness operates at the daylight brightness level.

15 (RW) Maximum current setting for the backlight when brightness
16 is at one of the three levels (daylight, office or dark). This

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