sysfs interface for analog devices adp5520(01) backlight driver |

--------------------------------------------------------------- |

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

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