   4 The backlight brightness control operates at three different levels for the
   5 adp8860, adp8861 and adp8863 devices: daylight (level 1), office (level 2) and
   6 dark (level 3). By default the brightness operates at the daylight brightness
   7 level.

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