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 ?
