In some cases it was not possible to follow the appropiate power ON/OFF sequence like in cases where the PGA needs to be enabled before the driver and disabled before the PGA for pop reduction.
Add a widget to support output driver (speaker, haptic, vibra, etc) drivers where power ON/OFF ordering is important.
