| 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. |
