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
|
|
devices. If enabled and VBUS is inserted, device will start to do the BC12
|
|
port detect and report the usb port type when port detect is done. See
|
|
datasheet for details. Normally controlled when TypeC/USBPD port integrated.
