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

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

-What: /sys/class/backlight/<backlight>/ambient_light_zone
-Date: May 2011

-Contact: device-drivers-devel@blackfin.uclinux.org
-Description:
- Get/Set current ambient light zone. Reading returns
- integer between 1..5 (1 = daylight, 2 = bright, ..., 5 = dark).
- Writing a value between 1..5 forces the backlight controller
- to enter the corresponding ambient light zone.
- Writing 0 returns to normal/automatic ambient light level
- operation. The ambient light sensing feature on these devices
- is an extension to the API documented in
- Documentation/ABI/stable/sysfs-class-backlight.
- It can be enabled by writing the value stored in
- /sys/class/backlight/<backlight>/max_brightness to
- /sys/class/backlight/<backlight>/brightness. \ No newline at end of file
