    ACPI / AC: Add a blacklist with PMIC ACPI HIDs with a native charger driver · af3ec837
    Hans de Goede authored
    On some systems we have a native PMIC driver which provides Mains
    monitoring, while the ACPI ac driver is broken on these systems
    due to bad DSTDs or because we do not support the proprietary and
    undocumented ACPI opregions these ACPI battery devices rely on
    (e.g. BMOP opregion).
    
    This leads for example to a ADP1 power_supply which reports
    itself as always online even if no mains are connected.
    
    This commit adds a blacklist with PMIC ACPI HIDs for which we've a
    native charger or extcon driver and makes the ACPI ac driver not
    register itself when a PMIC on this list is present.
