Anthony Koo 2ad0cdf9e2 drm/amd/display: set minimum abm backlight level ... [Why] A lot of the time, the backlight characteristic curve maps min backlight to a non-zero value. But there are cases where we want the curve to intersect at 0. In this scenario even if OS never asks to set 0% backlight, the ABM reduction can result in backlight being lowered close to 0. This particularly can cause problems in some LED drivers, and in general just looks like backlight is completely off. [How] Add default cap to disallow backlight from dropping below 1% even after ABM reduction is applied.
