Linux/AM3358: TI OMAP Jacinto 5 support for wake up resource from DeepSleep[Suspend to RAM]

Part Number: AM3358

Tool/software: Linux

Hi TI Team,

We are able to put the system in standby and wake-up with UART and USB interrupt sources.

Commands for enabling the wake sources:

echo enabled > /sys/devices/platform/ocp/44e09000.serial/tty/ttyO0/power/wakeup

echo enabled > /sys/devices/platform/ocp/47400000.usb/47401300.usb-phy/power/wakeup

echo 1 > /sys/power/pm_debug_messages

echo standby > /sys/power/state

with the above commands system is going to suspend & resuming (when we insert pendrive or any key press keyborad)

Same steps followed to put the system in deepsleep with the command

echo mem > /sys/power/state

System is going to suspend but it is not resuming from the deep sleep ,though configured UART & USB as a wake up resource 

In TRM it is observed that wake up functionality is supported from deep sleep

But in one of the TI wiki it is mentioned wake up from deep sleep is not supported yet()

Could you please confirm whether the wake up from deep sleep is supported or not?

If it is supported what are the configuration/changes are required?

Note:- we used CM3 firmware version (am335x-pm-firmware.elf)0x192 & am335x-bone-scale-data.bin firmware.
