5Description:
6		This entry allows enabling the sysoff mode of rt9471 charger devices.
7		If enabled and the input is removed, the internal battery FET is turned
8		off to reduce the leakage from the BAT pin. See device datasheet for details.
9		It's commonly used when the product enter shipping stage. After entering
10		shipping mode, only 'VBUS' or 'Power key" pressed can make it leave this
11		mode. 'Disable' also can help to leave it, but it's more like to abort
12		the action before the device really enter shipping mode.

23Description:
24		This entry allows enabling the USB BC12 port detect function of rt9471 charger
25		devices. If enabled and VBUS is inserted, device will start to do the BC12
26		port detect and report the usb port type when port detect is done. See
27		datasheet for details. Normally controlled when TypeC/USBPD port integrated.
