<!-- Array of desired screen brightness in nits corresponding to the lux values
in the config_autoBrightnessLevels array. The display brightness is defined as the measured
brightness of an all-white image.
If this is defined then:
- config_autoBrightnessLcdBacklightValues should not be defined
- config_screenBrightnessNits must be defined
- config_screenBrightnessBacklight must be defined
This array should have size one greater than the size of the config_autoBrightnessLevels
array. The brightness values must be non-negative and non-decreasing. This must be
overridden in platform specific overlays -->

<!-- Array of light sensor lux values to define our levels for auto backlight brightness
support.
The N entries of this array define N + 1 control points as follows:
(1-based arrays)
Point 1: (0, value[1]): lux <= 0
Point 2: (level[1], value[2]): 0 < lux <= level[1]
Point 3: (level[2], value[3]): level[2] < lux <= level[3]
...
Point N+1: (level[N], value[N+1]): level[N] < lux
The control points must be strictly increasing. Each control point
corresponds to an entry in the brightness backlight values arrays.
For example, if lux == level[1] (first element of the levels array)
then the brightness will be determined by value[2] (second element
of the brightness values array).
Spline interpolation is used to determine the auto-brightness
backlight values for lux levels between these control points.
