About our custom device enter into standby mode (i.e echo mem > /sys/power/state ) PMIC_STBY_REQ pin(ball U9) become high ,but we observed any change in the output voltage changes of PF3000 (like VDD_ARM_SOC_IN ) .please suggest related driver implementation or any suggestion.

Hi Analogics
these settings are defined in uboot, please check for example mx6ull_ddr3_arm2.c,
function power_init_board()
