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.

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

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.
