My test-bbb-suspend script seems to have:
sudo modprobe wkup_m3_ipc
sudo modprobe pm33xx
sudo modprobe rtc-omap
rtcwake -m mem -s 5
I think the same should work for am437x. But some boards do not support
deep sleep like am437x-idk.

You might get some info with no_console_suspend, but that might also
cause other issues.
