^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 552) * Bay Trail SoC + AXP288 PMIC, Type-C, DMI_BOARD_NAME: "815D"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 553) * Cherry Trail SoC + AXP288 PMIC, Type-C, DMI_BOARD_NAME: "813E"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 554) * Cherry Trail SoC + TI PMIC, Type-C, DMI_BOARD_NAME: "827C" or "82F4"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 555) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 556) * The variants with the AXP288 + Type-C connector are all kinds of special:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 557) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 558) * 1. They use a Type-C connector which the AXP288 does not support, so when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 559) * using a Type-C charger it is not recognized. Unlike most AXP288 devices,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 560) * this model actually has mostly working ACPI AC / Battery code, the ACPI code
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 561) * "solves" this by simply setting the input_current_limit to 3A.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 562) * There are still some issues with the ACPI code, so we use this native driver,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 563) * and to solve the charging not working (500mA is not enough) issue we hardcode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 564) * the 3A input_current_limit like the ACPI code does.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 565) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 566) * 2. If no charger is connected the machine boots with the vbus-path disabled.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 567) * Normally this is done when a 5V boost converter is active to avoid the PMIC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 568) * trying to charge from the 5V boost converter's output. This is done when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 569) * an OTG host cable is inserted and the ID pin on the micro-B receptacle is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 570) * pulled low and the ID pin has an ACPI event handler associated with it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 571) * which re-enables the vbus-path when the ID pin is pulled high when the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 572) * OTG host cable is removed. The Type-C connector has no ID pin, there is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 573) * no ID pin handler and there appears to be no 5V boost converter, so we
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 574) * end up not charging because the vbus-path is disabled, until we unplug
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 575) * the charger which automatically clears the vbus-path disable bit and then
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 576) * on the second plug-in of the adapter we start charging. To solve the not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 577) * charging on first charger plugin we unconditionally enable the vbus-path at
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 578) * probe on this model, which is safe since there is no 5V boost converter.
