From: Joshua Aberback <[email protected]> [Why] In some cases during topology changes, a pipe that was used to drive a stream being removed can be re-assigned to drive a different stream. In these cases, DSC power gating is not handled properly, leading to situations where DSC is being setup while power gated.
