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

13Description:
14		(RO) 13-bit conversion value for the first light sensor—high
15		byte (Bit 12 to Bit 8). The value is updated every 80 ms (when
16		the light sensor is enabled).

23Description:
24		(RW) Read or write the specific level at which the backlight
25		operates. Value "0" enables automatic ambient light sensing, and
26		values "1", "2" or "3" set the control to daylight, office or
27		dark respectively.

36Description:
37		(RW) Maximum current setting for the backlight when brightness
38		is at one of the three levels (daylight, office or dark). This
39		is an input code between 0 and 127, which is transformed to a
40		value between 0 mA and 30 mA using linear or non-linear
41		algorithms.

53		input code between 0 and 127, which is transformed to a value
54		between 0 mA and 30 mA using linear or non-linear algorithms.
