25		Control the dim brightness for <ambient light zone>
26		on this <backlight>. Values are between 0 and 127, typically
27		set to 0. Full off when the backlight is disabled.
28		This file will also show the dim brightness level stored for

35Description:
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)

45Description:
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.
