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.
