559 * using a Type-C charger it is not recognized. Unlike most AXP288 devices,
566 * 2. If no charger is connected the machine boots with the vbus-path disabled.
569 * an OTG host cable is inserted and the ID pin on the micro-B receptacle is
571 * which re-enables the vbus-path when the ID pin is pulled high when the
572 * OTG host cable is removed. The Type-C connector has no ID pin, there is
574 * end up not charging because the vbus-path is disabled, until we unplug
575 * the charger which automatically clears the vbus-path disable bit and then
576 * on the second plug-in of the adapter we start charging. To solve the not
577 * charging on first charger plugin we unconditionally enable the vbus-path at
