Description:
 
36
                Get conversion value of the light sensor.
 
37
                This value is updated every 80 ms (when the light sensor
 
38
                is enabled). Returns integer between 0 (dark) and
 
39
                8000 (max ambient brightness)

Description:
 
46
                Get/Set current ambient light zone. Reading returns
 
47
                integer between 1..5 (1 = daylight, 2 = bright, ..., 5 = dark).
 
48
                Writing a value between 1..5 forces the backlight controller
 
49
                to enter the corresponding ambient light zone.
 
50
                Writing 0 returns to normal/automatic ambient light level
 
51
                operation. The ambient light sensing feature on these devices
 
52
                is an extension to the API documented in
 
53
                Documentation/ABI/stable/sysfs-class-backlight.
 
54
                It can be enabled by writing the value stored in
 
55
                /sys/class/backlight/<backlight>/max_brightness to
 
56
                /sys/class/backlight/<backlight>/brightness.
