38c2ecf20Sopenharmony_ci
48c2ecf20Sopenharmony_ciThe backlight brightness control operates at three different levels for the
58c2ecf20Sopenharmony_ciadp5520 and adp5501 devices: daylight (level 1), office (level 2) and dark
68c2ecf20Sopenharmony_ci(level 3). By default the brightness operates at the daylight brightness level.

148c2ecf20Sopenharmony_ciDescription:
158c2ecf20Sopenharmony_ci		(RW) Maximum current setting for the backlight when brightness
168c2ecf20Sopenharmony_ci		is at one of the three levels (daylight, office or dark). This
178c2ecf20Sopenharmony_ci		is an input code between 0 and 127, which is transformed to a
188c2ecf20Sopenharmony_ci		value between 0 mA and 30 mA using linear or non-linear
198c2ecf20Sopenharmony_ci		algorithms.

278c2ecf20Sopenharmony_ciDescription:
288c2ecf20Sopenharmony_ci		(RW) Dim current setting for the backlight when brightness is at
298c2ecf20Sopenharmony_ci		one of the three levels (daylight, office or dark). This is an
308c2ecf20Sopenharmony_ci		input code between 0 and 127, which is transformed to a value
318c2ecf20Sopenharmony_ci		between 0 mA and 30 mA using linear or non-linear algorithms.
