So I'm ok with the requirement that we turn clocks on to change rates, but I wonder if in this case we need to turn on the clock that's changing rates itself, or if we just need to turn on the parent and/or future parent of the clock during the rate switch. Care to elaborate on that? --=20 Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
