Why? I know why because I'm CCed on the internal bug but nobody else knows what's going on here. Please clearly describe what you're fixing, i.e. that you're seeing black screens on sc7180 because the gdsc is being enabled/disabled so rapidly that the hardware is getting borked. Lots more detail please. Otherwise we're going to ignore this patch series as nonsense because we don't have enough information to realize that it is important.
