| 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. | |

| Description: | |
| This entry allows enabling the USB BC12 port detect function of rt9471 charger | |
