| 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. | |
