Hi all


I want to clearfy how to wakeup from standby by PMIC_STBY_REQ.


I tested wakeup from standby by PMIC_STBY_REQ both MCIMX6DL-SDP and SABRE-AI.

But SABRE-AI have never wakedup by PMIC_STBY_REQ.


could someone answer following question ?



I use following command to enter standby mode.


echo mem > /sys/power/state


Is it same effect on both board ?




When I use echo mem > /sys/power/state command, the vstby bit will set.

Am I correct ?




I found that the MCIMX6DL-SDP have PWR_BTN_SNS signal but SABRE-AI doesn't have it.

Does user need to add PWR_BTN_SNS signal for wakeup from standby by PMIC_STBY_REQ ?
