In sleep mode only AWAKE and RESET commands are allowed, so before sending the poweroff notification command resume from sleep mode and then send the notification command. PowerOff Notify is tested on a Synopsis Designware Host Controller (eMMC 4.5). The suspend to RAM and resume works fine.

The timeout value chosen is 300ms since that has proven enough for the problematic cards found, but could be increased if other cards require this.
