What: /sys/class/power_supply/rt9471-*/sysoff_enable Date: Feb 2023 KernelVersion: 6.3 Contact: ChiYuan Huang cy_huang@richtek.com Description: This entry allows enabling the sysoff mode of rt9471 charger devices. If enabled and the input is removed, the internal battery FET is turned off to reduce the leakage from the BAT pin. See device datasheet for details. It's commonly used when the product enter shipping stage. After entering shipping mode, only 'VBUS' or 'Power key" pressed can make it leave this mode. 'Disable' also can help to leave it, but it's more like to abort the action before the device really enter shipping mode.
