VDDARM Voltage

What is the Freescale recommended operation mode for the VDDARM voltage if the design uses the MMPF0100 PMIC?  Our Design implementation for the PMIC matches the Sabre Smart Devices Platform.  


Is there any advantage to running in the Analog regulation mode if PMIC supplies the ARM and the SOC voltage from separate buck converters as the PMIC MMPF0100?



If you are using the Analog regulation mode, why bother to change voltage when the CPU changes frequency since a voltage change will just dissipate the power in the internal LDO which is in the iMX6?
