Occasionally USB cannot be used after the system restarts

Hi,

It seems an issue that similar to this one. We are still investigating why custom board will hit this problem.

Is it possible for you to see if adding a power supply to PMIC_BBAT will enhance this case?

The value of PLLU_DIV seems to be normal if [CPU pin235:PMIC_BBAT] is high when the CPU is powered on.
