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. 13 14 Access: Read, Write 15 Valid values: 16 - 1: enabled 17 - 0: disabled 18 19What: /sys/class/power_supply/rt9471-*/port_detect_enable 20Date: Feb 2023 21KernelVersion: 6.3 22Contact: ChiYuan Huang <cy_huang@richtek.com> 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. 28 29 Access: Read, Write 30 Valid values: 31 - 1: enabled 32 - 0: disabled 33
