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()

uboot-imx.git - Freescale i.MX u-boot Tree
