| 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. |
