1. A device comprising:
an interconnect fabric comprising one or more nodes;
an end point device coupled to the interconnect fabric via an asynchronous device;
a clock controller coupled to provide a clock signal to the one or more nodes, wherein, based on the clock signal, the one or more nodes are to communicate with the end point device via the asynchronous device while a first clock domain comprises the one or more nodes, and while a second clock domain comprises the end point device; and
a power management (PM) controller to communicate a control signal to the clock controller while the clock signal is cycled at a first frequency, wherein the control signal indicates that the first clock domain is to be transitioned from the first frequency to a second frequency;
wherein, in response to the control signal, the clock controller is to stall the clock signal throughout a period of time which is equal to or greater than a duration of three cycles of a lower one of the first frequency or the second frequency, and after the period of time, to cycle the clock signal at the second frequency.
