27* Brightness limit to be used after the driver has been probed. This is useful
28* when it is not known how much power is available for the backlight during
29* probe.
30* Valid range 0-63. Can be changed later with pcf50633_bl_set_brightness_limit.

34* When changing the backlights brightness the change is not instant, instead
35* it fades smooth from one state to another. This value specifies how long
36* the fade should take. The lower the value the higher the fade time.
