1sysfs interface for analog devices adp8860 backlight driver 2----------------------------------------------------------- 3 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. 8 9See also /sys/class/backlight/<backlight>/ambient_light_level and 10/sys/class/backlight/<backlight>/ambient_light_zone. 11 12 13What: /sys/class/backlight/<backlight>/l1_daylight_max 14What: /sys/class/backlight/<backlight>/l2_office_max 15What: /sys/class/backlight/<backlight>/l3_dark_max 16Date: Apr, 2010 17KernelVersion: v2.6.35 18Contact: Michael Hennerich <michael.hennerich@analog.com> 19Description: 20 (RW) Maximum current setting for the backlight when brightness 21 is at one of the three levels (daylight, office or dark). This 22 is an input code between 0 and 127, which is transformed to a 23 value between 0 mA and 30 mA using linear or non-linear 24 algorithms. 25 26 27What: /sys/class/backlight/<backlight>/l1_daylight_dim 28What: /sys/class/backlight/<backlight>/l2_office_dim 29What: /sys/class/backlight/<backlight>/l3_dark_dim 30Date: Apr, 2010 31KernelVersion: v2.6.35 32Contact: Michael Hennerich <michael.hennerich@analog.com> 33Description: 34 (RW) Dim current setting for the backlight when brightness is at 35 one of the three levels (daylight, office or dark).
