i.MX6 VDDHIGH_IN power-up sequence

   I am currently developing a board with the i.MX6 and I intend to use the PMIC MMPF0100F0 with its pre-programmed OTP configuration. I would like to know if it is possible to power the VDDHIGH_IN rail after powering VDDARM and VDDSOC power rails.


   As shown on the picture below, the SW2 (+3V3) is the 5th rail to power-up and I wonder if it can cause any problem while booting. 


   Thank you!
