5Description:
6 This entry allows enabling the sysoff mode of rt9467 charger
7 devices.
8 If enabled and the input is removed, the internal battery FET
9 is turned off to reduce the leakage from the BAT pin. See
10 device datasheet for details. It's commonly used when the
11 product enter shipping stage. After entering shipping mode,
12 only 'VBUS' or 'Power key" pressed can make it leave this mode.
13 'Disable' also can help to leave it, but it's more like to
14 abort the action before the device really enter shipping mode.
