    Subject[PATCH 5.13 216/800] platform/x86: touchscreen_dmi: Add an extra entry for the upside down Goodix touchscreen on Teclast X89 tablets
    Date
    From: Hans de Goede <hdegoede@redhat.com>

    [ Upstream commit a22e3803f2a4d947ff0083a9448a169269ea0f62 ]

    Teclast X89 tablets come in 2 versions, with Windows pre-installed and with
    Android pre-installed. These 2 versions have different DMI strings.

    Add a match for the DMI strings used by the Android version BIOS.

    Note the Android version BIOS has a bug in the DSDT where no IRQ is
    provided, so for the touchscreen to work a DSDT override fixing this
    is necessary as well.
