Retimers in H/w usually takes 30 to 40ms to wake up all the devices. To get this we use the Extended Wake Time feature in which the sink device tells us the minimum amount of time it requires to wake up and we need to do a write to grant this request else we need to wake up within 1ms of low power state exit.
