Len Brown reported the system resume time is taking more than 2 seconds in bug - https://bugzilla.kernel.org/show_bug.cgi?id=185621. The reason of the 2 seconds is due to the firmware download time. The chip is booted up in the default reference clock speed to handle the firmware download to chip memory and advanced to the support higher speed clock to run the firmware after all. The default reference clock in the hardware is slow so that the firmware download time is taking up to 2 seconds for a 600KB firmware file.

This can help to improve the firmware download time from 2 seconds to around 500ms for the same 600KB firmware file.
