+What: /sys/class/power_supply/rt9471-*/sysoff_enable
+Date: Feb 2023
+KernelVersion: 6.3
+Contact: ChiYuan Huang <cy_huang@richtek.com>
+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.

+What: /sys/class/power_supply/rt9471-*/port_detect_enable
+Date: Feb 2023
+KernelVersion: 6.3
+Contact: ChiYuan Huang <cy_huang@richtek.com>
+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.
