While this is in general a good idea (because of broken DSDT or proprietary and undocumented ACPI opregions for the ACPI AC devices) there are some Cherry Trail devices which use a separate charger controller despite the AXP288 having a builtin charger. The net effect of blacklisting the ACPI drivers is that on these devices the AC reporting is broken since the AXP288 PMIC charger bits are not actually used on this hardware. This commit adds an ac_do_not_check_pmic quirk for this and sets this on the 2 devices currently known to use a separate FG controller, the ECS EF20EA and the Lenovo Ideapad Miix 320. [hdegoede@redhat.com: Merge the quirk handling and the adding of the DMI table entry into 1 commit, add a second DMI entry for the Miix 320.] Signed-off-by: Carlo Caione <carlo@endlessm.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J.
