+Description:
+ This entry allows enabling the sysoff mode of rt9467 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.
+
+ Access: Read, Write
+ Valid values:
+ - 1: enabled
+ - 0: disabled
