* The HP Pavilion x2 10 series comes in a number of variants:
* Bay Trail SoC + AXP288 PMIC, DMI_BOARD_NAME: "815D"
* Cherry Trail SoC + AXP288 PMIC, DMI_BOARD_NAME: "813E"
* Cherry Trail SoC + TI PMIC, DMI_BOARD_NAME: "827C" or "82F4"
*
* The variants with the AXP288 PMIC are all kinds of special:
*
* 1. All variants use a Type-C connector which the AXP288 does not support, so
* when using a Type-C charger it is not recognized. Unlike most AXP288 devices,
* this model actually has mostly working ACPI AC / Battery code, the ACPI code
* "solves" this by simply setting the input_current_limit to 3A.
* There are still some issues with the ACPI code, so we use this native driver,
* and to solve the charging not working (500mA is not enough) issue we hardcode
* the 3A input_current_limit like the ACPI code does.
*
* 2. If no charger is connected the machine boots with the vbus-path disabled.
* Normally this is done when a 5V boost converter is active to avoid the PMIC
* trying to charge from the 5V boost converter's output. This is done when
* an OTG host cable is inserted and the ID pin on the micro-B receptacle is
* pulled low and the ID pin has an ACPI event handler associated with it
* which re-enables the vbus-path when the ID pin is pulled high when the
* OTG host cable is removed. The Type-C connector has no ID pin, there is
* no ID pin handler and there appears to be no 5V boost converter, so we
* end up not charging because the vbus-path is disabled, until we unplug
* the charger which automatically clears the vbus-path disable bit and then
* on the second plug-in of the adapter we start charging. To solve the not
* charging on first charger plugin we unconditionally enable the vbus-path at
* probe on this model, which is safe since there is no 5V boost converter.
