In i.MX6 processor family, for DVFS to work successfully , is it neccessary that Internal Digital LDOs are for powering on ARM , SoC & PU ?
Is there a method to make DVFS work when the digital LDOs are used in bypass mode ?
My concern here is if we use LDOs , drop across the LDOs itself will result in power consumption .
If we can control the DC-DC converer present externally for DVFS , this voltage drop across LDO can be eliminated.
Please share your thoughts.
