| Subject: platform/x86: touchscreen_dmi: Add an extra entry for the upside down |
| Goodix touchscreen on Teclast X89 tablets |
| |
| 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. |
