While running the DisplayPort simulation, if the simulation is abruptly switched off, AUX and CTRL may continue processing like in a normal DisplayPort connected mode. This may result in an unstable DP driver state and may affect subsequent hot plugs. Abort the AUX and CTRL processing when DP simulation is switched off. This brings the DP driver into stable state when simulation is switched off.
