High-precision brightness will set the brightness level from bl_min_level to bl_max_level. If we enable 12bit brightness, in fact, the hardware will not tolerate very low brightness such as level '1 - 9' in liberty, these levels cause the backlight unstable. So we have to define the minimum brightness by 'qcom,mdss-dsi-bl-min-level' that the driver does not set the backlight level below that.
