power on without PMIC

Hi community,

I'm working on i.MX6 DL sabreSD board without PMIC.

I build image with Android 6 source code.


After I read the document "i.MX Linux® Reference Manual" I tried to modify Power Management configuration in menuconfig to disabled it.

These were what I had done.

disabled CONFIG_PM


disabled PF100 Regulator Driver

disabled Anatop Regulator Driver


But after I disabled all this configuration and rebuild image, it showed error to me and said there is something undeclared.


I am afraid that it will cause the system cannot reboot normally or it would dead when I starting the kernel.


Here are my questions:

  1. Can I use the same image which included power management on the board which have no PMIC?
  2. If can't what can I do ? Did I just need to set all configurations which are related with PMIC to disabled or I have to modify driver to fitch board which have no PMIC?


Thanks in Advanced!
