Dear Otavio Salvador,

Do I understand correctly that this happens only with the FSL kernel, i. e. not with mainline Linux?
Exactly.
What exactly is the effect of calling your set_anatop_bypass() function? Why would that be needed on the FSL kernel, and not on mainline?
Mainline seems to not drive the pmic while the FSL kernel does. So it seems we ought to bypass the internal LDO.
Or rather fix the FSL kernel?
I am not sure the kernel is wrong here.
As I said in previous message, the mainline kernel does not drive the PMIC and the power sources are the internal LDO. The FSL kernel changes the power sources to the ones from the PMIC (which makes sense) but in the end it depends on U-Boot have done it too.
