See device datasheet for details. 9*ab8174bbSChiYuan Huang It's commonly used when the product enter shipping stage. After entering 10*ab8174bbSChiYuan Huang shipping mode, only 'VBUS' or 'Power key" pressed can make it leave this 11*ab8174bbSChiYuan Huang mode. 'Disable' also can help to leave it, but it's more like to abort 12*ab8174bbSChiYuan Huang the action before the device really enter shipping mode. 13*ab8174bbSChiYuan Huang 14*ab8174bbSChiYuan Huang Access: Read, Write 15*ab8174bbSChiYuan Huang Valid values: 16*ab8174bbSChiYuan Huang - 1: enabled 17*ab8174bbSChiYuan Huang - 0: disabled 18*ab8174bbSChiYuan Huang 19*ab8174bbSChiYuan HuangWhat: /sys/class/power_supply/rt9471-*/port_detect_enable 20*ab8174bbSChiYuan HuangDate: Feb 2023 21*ab8174bbSChiYuan HuangKernelVersion: 6.3 22*ab8174bbSChiYuan HuangContact: ChiYuan Huang <cy_huang@richtek.com> 23*ab8174bbSChiYuan HuangDescription: 24*ab8174bbSChiYuan Huang This entry allows enabling the USB BC12 port detect function of rt9471 charger 25*ab8174bbSChiYuan Huang devices.
