  From i.MX6 QuadPlus datasheet the VDD_ARM_IN+ADD_ARM23_IN maximum current is 3.73A and VDD_SOC_IN is 3.7A, the NXP QuadPlus reference design(SCH-28615) powered VDD_ARM_IN+ADD_ARM23_IN by PMIC SW2 and VDD_SOC_IN by PMIC SW1, according to the PMIC datahsheet SW2 output capacity is 2.5A and SW1 output capacity is 4.5A, so SW2 canot provide 3.7A current to QuadPlus, I am not sure is it spec error or NXP reference design error? How to use PF0100 F9 or FA OTP to power QuadPlus?
