I'm working on a custom board with an iMX6 Solo processor.
VDDARM_IN, and VDDSOC_IN are powered at 1.2V by a DCDC with less than 5% Vpp ripple.
My doubt is about the difference between bypassing LDOs or setting them with an output voltage greater than output.
As Igor said:

in LDO turning from 0x1F to 0x1E cause i.MX6DL hang
I understand that the "power" part of LDOs work in exactly same way and the only difference is that when bypassing the control/analog part of LDO is disabled. Am I wrong?
Which LDOs configuration do you recommend us in case we want to use Arm at 972MHz and GPU as well?
Thanks in advance!
