i.MX6SL VDD_ARM_IN minimum voltage with PF3000

[ko-hey]

Hi all

Let me confirm about input voltage from PF3000 to VDD_ARM_IN of i.MX6SL.

The device is as below.

・CPU：MCIMX6L2EVN10AB

・PMIC：MC32PF3000A4EP

According to the table 9 of IMX6SLCEC, the min voltage of VDD_ARM_IN for operation at 996MHz is 1.375V.

On the other hand, the voltage setting for SW1A of MC32PF3000A4EP is 1.375V.

Q1.

According to the above value, I think I need to set more higher value for SW1A after boot up.

Because there are no margin between them.

Do you recommend to set more higher value for SW1A ?

Q2.

If Q1 is yes, please tell me the recommendation value.
