Subject: [PATCH 5.12 203/700] platform/x86: touchscreen_dmi: Add an extra entry for the upside down Goodix touchscreen on Teclast X89 tablets
From: Hans de Goede <hdegoede@...hat.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.
