When powering off, a shutdown command needs to be sent to the MCU. When the power button is long pressed, the MCU will send a shutdowncommand to the system. If system does not shutdown within 60 seconds,the power will be turned off directly. MCU only provides voltage for charger and battery. Manufacturer removed RK8xx PMIC.
Unless the design of the board is proprietary, it would be good to provide a link to the board schematic, for those interested in verifying the board DT file. As a note, I already tried to find the board schematic with no success, so the design might be proprietary.
